Follow along as I build an 8-bit computer. This time we have a look at the power supply and why decoupling capacitors are always absolutely necessary. To demonstrate the concept, I use LTspice to simulate the torture of a poor little 555 timer connected to a power supply through a 50cm cable without a decoupling capacitor.

This video is a continuation of my previously posted Two Sources of Amplifier Hum Video, and explains (in very basic language) the different methods of rectification used in amplifiers and how the filter capacitors function to eliminate the 120 cycle/sec ripple (hum) that remains after the 60 cycle/sec current is rectified. In addition a comparison of commonly used guitar amp rectifier tubes is presented, and different types of diode (solid state) rectification are discussed. PLEASE NOTE: There is an error in the diagram for Half Wave Rectification. The output should be labelled "120VDC (169VDC RMS)" instead of 60VDC. With half-wave rectification, you get approximately the same voltage out of the single diode that you put in, but only half the current, since the negative portions of the waveform (i.e. half the current) are blocked.

Boutique Guitar Amplifier sound clips of the The Michael Charles Music Inc. Non-Master, point to point hand wired, 12 Watt RMS, lightweight, compact 4 lb. 7 oz. 7" X 5" X 5" amp proudly made in the USA. Despite it's deceptive size The Michael Charles Music Inc.12 Watt, designed by Dan McCue of Lustone Amps, this small yet powerful amplifier features ultra pure tone, wide sonic versatility, extreme touch sensitivity and five power filter stages for super quiet operation even at it's top volume of up to 116 db. The 12 Watt is carefully point to point hand wired with tight component connections and minimal solder while using the shortest wire and component lead lengths possible to reduce signal resistance resulting in better tone. Big advantages of the 12 Watt's "Overlooked" tubes: The 12 Watt uses 6AQ5 power tubes & a single 6C4 in it's phase inverter. There are a number of excellent tubes major amp companies virtually never made amps with that sound great. These are two of the, "overlooked" tubes. What that means to you.... While 6AQ5 & 6C4 tubes are no longer in production, they are super cheap & easily available in many NOS tube warehouses, on eBay, Amazon & our store keeps them on hand. There are literally millions of them all over the world averaging $5 - $10 a piece. You can completely re-tube the 12 Watt for as little as $25. Also the 12 Watt's power tubes do not need to be biased or matched. Any two 6AQ5's will work as long as they are the same make and model. For example: 2 GE 6AQ5A's, or 2 GE 6AQ5W's 2 RCA 6AQ5A's, or 2 RCA 6AQ5W's 2 Mullard 6AQ5's Preamp tubes can be, 12AX7, 12AY7, 12AT7 or 12AU7. Tubes the amp comes with: 1 Chinese 12AX7 preamp tube 1 GE 6C4 phase inverter tube (Basically a 12AX7 with only one triode) 2 GE 6AQ5W power tubes (Mini versions of the 6V6) Upgrade options: #1 Three way switch giving the choice of selecting different capacitors within the circuit to change the tone and frequency response for bright boost, bass boost or an unaltered sound. #2 An in-unit power line filter to correct electricity flow where "less than perfect power" lurks and make the amp even quieter. #3 20 watt power & output transformers allowing for more headroom, volume & individual 4, 8, or 16 Ohm speaker outputs #4 Audio frequency and power supply filter choke: tightens bass response, enhances mids and highs by smoothing power ripple for a more open, tight sound.

From........lostsailors.com....... Larry Honigbaum Founder and leader of Lost Sailors, Larry plays lead guitar, sings the lead vocal on most of the songs, and is in charge of choosing what songs we play at the shows; that is, he is our "Jerry". Larry's been playing Grateful Dead music since he was a teenager, has been to over 350 Grateful Dead shows, and is an avid tape trader and gets all his news from The Onion. Before forming Lost Sailors, Larry headed up another Ithaca-area Grateful Dead tribute band, Group Effort, which recorded a number of his original compositions in addition to the GD covers. The youngest of the members of Lost Sailors, he nonetheless has the most experience with the Grateful Dead's milieu, and takes great care in crafting the tone and style of Lost Sailors performances. Eric Ott Eric plays bass guitar, sings lead on those songs Larry doesn't -- primarily the "Bobby tunes" -- and like Phil in the Grateful Dead, is in charge of the Forces of Nature. He's got a deep grounding in jazz and blues in addition to the GD repertoire, and plays with a number of other bands and combos in the Ithaca and Trumansburg areas. He was also for many years the King of Rongovia, leading that venerable institution known as The Rongovian Embassy through its finest years of glory and fame. Eric's studied patience and solid grasp are legendary in the annals of Lost Sailors. He is our rock, our foundation. Taz Cannon Our drummer is the Tasmanian Devil himself: the percussive master of the pots, pans, and skins. He is The Man In Charge of The Groove. He's got the tough job of covering both Mickey and Billy's legacy, which he does with a patented combination of maniacal positive energy and excess caffeine. Taz played blues and rock around Ithaca for decades with legends like Northern Tier, Fishheads, The Glenn Davis Band, Blue Shadows, Stark Raven, Everett Fox Band, All You Can Eat, Breaking Even, Skin Tight, and Pete Panek and the Blue Cats. He is an active local DJ and radio personality, and does his own shows at The Haunt. He is Lost Sailors' resident photographer and is responsible for capturing the images of a huge number of people in a 100-mile radius of Ithaca. On the personal side, Taz is an avid fancier of all things having to do with dragons, and is a serious audiophile, having a home entertainment setup second to none. He also hunts deer with his car, albeit unintentionally. Roy Flacco Roy is Lost Sailors' Wild Card. He plays the "Bobby" rhythm guitar parts, sings vocal harmonies, and simultaneously (as his alter ego Professor Flux Capacitor) engineers the Lost Sailors' sound system from the stage. He appears to travel through time, which we think has something to do with quantum tunneling. He first saw the Grateful Dead at his college homecoming on Bob Weir's birthday, but joining Lost Sailors was what brought out his inner Deadhead over his electric-blues-rocker. In an excess of enthusiasm he founded another spinoff Dead cover band Saints of Circumstance, playing in tandem with Lost Sailors from 1999 through 2002. Roy has a 16-track home recording studio where in addition to guitar he plays keyboards and bass (and percussion when he thinks nobody is watching), runs the Lost Sailors website and fanbase email, makes MP3s of the show tapes, and in his copious spare time solves the problems of achieving world peace. Neal Massa Neal is the most recently acquired full-time member of the band, Neal adds his exquisite keyboards to Lost Sailors, in addition to his many other musical activities around Ithaca. A veteran musician known to nearly every music lover in the area, he brings a particularly fine tonal setting to the Lost Sailors shows, that puts everybody in a much better place. The keyboard position in a Grateful Dead band is known to be dangerous if not outright lethal — so Neal was a little cautious about becoming a full member of the band for a while. However, he's been showing up much more often than not this past year, so we're gonna make it official...

A description of a typical Linear Voltage Power Supply covers the following information: 1. 0:55 Transformer to reduce AC Voltage from 240v to 24v. 2. 05:48 Rectification to convert the AC voltage into a pulsating DC voltage. 3. 13:01 Smoothing capacitor. How we smooth out the pulsating DC. 4. 15:32 The regulator is described that fixes the voltage to a constant value removing the remaining ripple voltage. Linear power supply advantages / disadvantages The use of any technology is often a careful balance of several advantages and disadvantages. This is true for linear power supplies which offer some distinct advantages, but also have their drawbacks. [ Linear PSU advantages ] Low noise: The use of the linear technology without any switching element means that noise is kept to a minimum and the annoying spikes found in switching power supplies are not present. Established technology: Linear power supplies have been in widespread use for many years and their technology is well established and understood. [ Linear PSU disadvantages ] Efficiency: In view of the fact that a linear power supply uses linear technology, it is not particularly efficient. Efficiencies of around 50% are not uncommon, and under some conditions they may offer much lower levels. Size: The use of linear technology means that the size of a linear power supply tends to be larger than other forms of power supply. Heat dissipation: The use of a series or parallel (less common) regulating element means that significant amounts of heat are dissipated and this needs to be removed. Despite the disadvantages, linear power supply technology is still widely used, although it is more widely used where low noise and good regulation are needed. One typical application is for audio amplifiers.

A noisy Fender in need arrives at D-Lab. Tubes were shot, microphonic, running hot, Hum, hiss, pops, you name it. Simply needed a few new tubes. However, it is always a good idea to give the amp a thorough inspection for bad solder joints, etc. If you are repairing one of these, I highly recommend a matched pair of EL84's from the TubeDepot. For a circuit board based amp, these are not bad sounding amps. I have replaced the output tubes with 6V6's in another video, which was a great improvement. Hope this info is of value to you. TD

In the second half of the video, an oscilloscope is used to present a step-by-step visual overview of the entire rectification process, including the smoothing of ripple with an electrolytic capacitor. I apologize for the camera's difficulty in focusing on the scope CRT, but hopefully it will not detract from the informative content of the presentation. Link to the video explaining how the filtered DC output can be much higher than the RMS rating of the power transformer: https://youtu.be/MXgG-0MIBGA Thanks for watching.

I am making this YouTube video because I have lost two high-end tubes in my McIntosh MC275. Both tubes were destroyed in the same manner in the same socket - the most left hand 6550 socket as viewed from the front of the amplifier. Then another incident occurred where a KT66 tube was destroyed in a McIntosh MC40 when the plate lead was accidentally broken. This made me realize that I was probably loosing plate voltage intermittently in my MC275 on the socket where the Genelex and then Telefunken tube was destroyed. The solution was tightening of the female pin(s) in the KT88 sockets on the MC275. I hope this video helps others diagnose possible loose pins in the sockets of tubes - especially those amplifiers that have multiple failures of output tubes. My theory is the plate and connecting wires conducts extra heat to pin 3 of the tube socket and over decades of use, softens the metal and the female pin looses solid electrical contact allowing the plate to become "open" even for a moment and damaging the screen grid of the output tube.Here is a link to an Eimac article on vacuum tubes. It is well worth reading starting at page 5 at "Selection of Tubes for Single Sideband". Even though the article is primarily for RF, the advice and wisdom on vacuum tube operational applies equally well for AF. file:///C:/Users/Admin/Downloads/Eimac%20application%20guide%209.pdf

This video discusses how to measure the ESR (equivalent series resistance) of a capacitor using an oscilloscope and function generator. All of the capacitors tested in this video were 220uF electrolytic caps. In reality, the resistance in the plates of a dried out electrolytic capacitor can't be modeled as a simple series resistor, but for the purposes of identifying good from bad, this simplification works fine. In the video, I show the ESR meter that I made in 2006.

The hum (not the buzz) that plagues single coil guitarists is cannot be solved using filters (or using DC for tube heaters). The hum is a result of the single coil picking up EMI from the power transformer and shifted 60 degrees by the tone stack. I demonstrate how a $6 audio transformer used as an inductor will reverse the 60 degree shift and silence the hum. This does not apply to humbuckers. This problem occurs in passive guitars and is more pronounced in guitars with on-board boosts, EQ circuits and other op-amp devices. The bass in the video is an Ibanez with a boost circuit. If you have spent money on upgrading components, tubes, filters, and other specialized and "highly recommended" equipment and still have a hum, then the hum problem is most likely a phase shift hum. To solve the buzz, a noise canceling circuit is required. My next EMI Shield (prototype 6) will cancel hum, cancel buzz, and correct for phase shift noise. The canceling circuits will be adjustable so that amount of hum and buzz can be dial out. Original Work, Copyright 2018 James D. Whiteside, II all rights reserved.

------------------------------ Click "Show More" -------------------------------------- In this video we will have a look at the MESR100 esr meter from MIB Instruments,We will have a look at the insides and test some components. For the price as an entry level esr meter i would recommend it the test leeds a bit short for in circuit testing But its a great little meter. Features: JINGYAN MESR-100 V2 Auto-ranging capacitor ESR and Low Ohm Meter Measuring range from 0.001 to 100.0R, support IN CIRCUIT Testing. Using true 100 KHz sine wave to measure the ESR value, which is equal to the testing method of capacitor manufacturer. What is ESR of capacitor? There is a series resistor inside a capacitor, by using 100kHz to remove the impedance 1/(2*pi*F*C), the impedance will become small, and we can then measure the true series resistor value. A bad E-capacitor will have a larger ESR and create a large ripple rather than filtering noise. Normally, a bad capacitor is larger than 3 ohm. Using this theory, we can measure to see if the capacitor is bad/ damaged or in good condition. Because this ESR meter only applies less than 15mV DC or peak to peak on a good capacitor, as a result it can be use as an in circuit tester as the low testing voltage will not turn on the semiconductor inside a circuit under test. Specification: 1) Accuracy: Up to 1% Wide Measurement Range: 1uF (for 0.1uF the error will be larger on equation 1/(2*pi*F*C) @ 100Khz ) 2) High Resolution: 4 digit, or 0.001Ohm @ 1 Ohm range 3) Measuring voltage: 40mV RMS (TESTING VOLTAGE) 4) Clamping voltage: 0.15V (open voltage) 5) Battery 2X AA 1.5V battery 6) External Power: 5V micro USB 7) Operating current 0.02A 8) Battery Life time: 80 Hours Thanks for watching, If you liked my videos and would like to support this channel you can make a donation @ http://goo.gl/GqtT4 or click the Show Your Support link, on are channel page and if you use bitcoins you can send us some bitcoins to 1MFGvF7NPaXC7RU5Trwo8z1dUbuowcuw5D Thanks for you support.

This video expands upon a concept presented in the "How Amps Work: The Power Supply" video regarding the configuration of the AC wave form and the differences between Peak AC Voltage and RMS. It also discusses the different ways that amplifier output power can be rated. Previous videos have established a basic foundation in amplifier design and function; now, subsequent videos will elaborate upon key concepts and hopefully provide more advanced insights. In addition, we recorded and uploaded this video in 720p HD, so it should have a lot better resolution than previous videos. Thanks for watching !!

general purpose multimeters are useful to measuer DC R however they are not enough for OPT test. withstanding voltage tester and precision LCR meter are used for perfect OPT test.

In this tutorial Dave explains how to precisely measure and calculate the remaining (or wasted) energy capacity in a battery using the graphical analysis technique using a spreadsheet. The differences between constant power and constant current loads and when to use them is discussed. Also, the importance of ESR and measuring the battery voltage under load is demonstrated. This is a particularly relevant to the Batteriser product and proof is provided that shows that even over the entire current range, the wasted energy in a battery can be no better than a few 10's of percent for a 1.1V cutout voltage. Blowing the batteriser claim of 80% wasted energy out of the water.

Yuin Huzami - The Ripple Effect - FKN DOPE! The Ripple Effect Album Launch 25/02/12 @ Alloneword Lyrics: This is for the core heads, feeling the force of the vortex Ready for anything, covered in gortex While heavenly hemispheres form double Taurus The Vatican erased what I'm sure Hubble sore It's a picture as vivid as the cisteen Fibonacci codes delivered in a sixteen A dual reality, I'm living it in split screen The path of angels trying to get into it's slip stream Escape from the mazes patterns through sacred passages Raised from the ashes of a blue flame capacitor Ancient practices erased and debased through a mainstream aperture It's not as far-fetched to me like Star Trek to Gene To master the teaching of star-tetrahedron I'm seeking some clarity, speaking of Harramien Reach inner balance while they preaching insanity The ripples, the ripples, the ripples, the ripples We got the ripple the ripple the ripple the ripple the ripple effect Unlock it, unblock it, we got the ripple the ripple the ripple the ripple the ripple effect I've been investing my time furnishing the mind Immaterial leisure, learning of the light Til my furnaces are bright enough to emanate the warmth Travel through the heart, premeditate a course The path that I walk is congruent with the nuances And fluent with druidic influences Never getting ruled by the foolishness around me That's compounding, lacking any grounding I peer into mysterious realms See who's really at the wheel when fear is at the helm Well acquainted with my enemy, I'm learning about the self Journeying within instead of yearning for the wealth Wily as a warlock, grimy as the raw rock Jaw dropped still waiting for the door knock To usher in the new age, proof that no government could ever prove fake to open up the true nature Unlock it, unblock it, we got the ripple the ripple the ripple the ripple the ripple effect Shamanic when I shine like a star planet Harmonic the truth I'm never far from it Unified fields electrify steel under car bonnets when I kick start sonnets, spittin sparks off it yo I charge from the heart often I'm paying art homage as a craft novice With insatiable learning, yearning, I can't stop it I'm not a heart throb or chart topper Just a smart cobba droppin metatron bombs on ya closed minds So blind don't notice the road signs Up ahead dead end for ya low vibes Float by on a course as the crow flies Connect with those collecting real worth Kinetically burst to energetically heal earth I feel the birth of realness, we're on the verge Let it emerge emitting a surge Through the universal words a verse on the song lines Gongs and chimes evoked by a strong mind It's been a long time coming around We rediscovered the knowledge embodied in our genes It begins in our dreams Tapping in to our surroundings Our ability to learn is compounding We learn quicker, unlock it faster With practice the novice becomes the master
