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.

Simple circuit that shows how a capacitor can block direct current and pass AC current through it explained. Another capacitor is used to show that capacitors can also sometimes hold either positive or negative voltage with a single DC power source if connected properly so you must be careful with polarized capacitors. Multimeter is used to take voltage measurements of both capacitors used.

I've been watching quite a number of #DIY #homeMade method on #YouTube #Videos about #HowTo remove noise from the LM386 audio amplifier circuit which can be done in a few ways. But here experimented a new way using mini step down transformer to remove the distorted sound and it turns out to be very effective which is near 100% free from noise. The problem with the LM386 IC is very sensitive to ground loop voltage. Even our fingers could actually disturb the signal. As you can see the crackling noise and sometimes hissing noise coming out even if there is no sound to amplifier (inactive states). But after using the step down transformer at the input to filter the noise and once again it is regulated at the output using coupled inductor the sound is simply amazing. In inactive states (no music / sound) the distorted noise is almost nothing which i think this is one of the perfect solution used by audio amplifier manufacturer Read the review circuit schematic diagram: http://howtodosteps.blogspot.my/2017/04/lm386-amplifier-circuit-schematic.html Watch alos audio amplifier electronic circuit: Hopefully this video gives an idea how to reduce / removed noise from the LM386 amplifier circuit.

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...

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 video for that is here: http://www.youtube.com/watch?v=bmYAgat-sOQ A copy of the video notes can be found here: http://www.qsl.net/w/w2aew//youtube/Measuring_capacitor_ESR.pdf

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.

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.

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.

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.
