View topic image gallery. Pinside member. Olgiate Olona. Hi everybody!! Accidentally I had a short between pin 4 and 5 of TDA amplifier.. I replaced it with a new one but now a big annoying buzz comes out from the speaker a very very big noise. What's happened? Please help me.. Tanks Ciao Loris. Since the other end of the speaker goes to ground did you kill the speaker by shorting 12v across it? Do you have another speaker to try? There are two transistors that do some amplification between the digital to analogue converter and the tda amp, i wouldn't think a pin 4 to 5 short on the tda would cause them to fail tho.

I've tried another little speaker.. Volume pot? Please help me to understand how it works and where I can check I would like to try another TDA ampli Could it be?

Is it possible you burned the feedback resistors? I don't have schematics for that sound board but I suspect it may be similar to the system 6 circuit. There may be a ohm on pin 4 that connects to a capacitor back to pin 2 and a 2. Depending on how long the pin short was in place, these resistors would have been fried.

Also make sure you test the board fully mounted to the game with mounting screws in place. I found that if the sound board is not grounded, strong feedback can result. Hi Schwaggs! Thanks also to you for the reply. The short has not been too long.. Correct, but that noise is very strong and tightening all the 4 screws doesn't improve the noise The board was just recapped.

All the electrolytic capacitors I mean. New capacitors, new sockets, new PIA Before the short the board working good I'm stupiiiid! Sound scheme. Also check C13 and C14 to make sure they are OK. I suspect they are, especially if you used 16V or higher caps there. You're welcome! Meanwhile here a little videoclip of the noise. Tomorrow I will replace C13, R24 and maybe I'll try another amplifier.. The situation is better but not enough.. Other suggestions? Have you tested the board in the game?

What are you using for the remote volume control? Is it possible the gain is just too high using only the volume adjustment on the sound board? For the moment I'm testing the board at bench. It is not the first time, and with other boards I didn't have this problem. This same board worked fine at bench before the short.. Sorry for my stupid question Which means the final "V"? Could be this my problem? I replaced the original TDAV with one As before, the noise is different and quiter but always present.

I bought a TDA but doesn't work.. I'stucked here. So, suggestions? Maybe a little bit "tinny" but is it that small speaker you are using on the bench? It sounds like a typical amp with the gain cranked to "11". Does the buzzing get quieter when the volume is turned down? What type of capacitor is C12? Maybe try replacing that cap?

No, turning the pot the buzzing remains the same. The cap is the original 1 mfd, tantalum but on the schematics is indicated as 0. Could be but as I said, other working boards have not this marked buzzing.

About the "tinny sound" Making an "experiment", raising the value of R19 ohm insted 2. Try pulling one leg of C12 and see if the buzzing goes away. If it is still there, the problem is in the amp stage.

I've seen a couple of videos on youtube. A very slighty sound comes from the speaker approaching the ear. Restoringthe cap in position with finger, the sound is like before, always disturbed.

I've tried another TDA from a working sound board but nothing changed. About C Who is right? I've a spare electrolytic 1 mfdV A technical question: I said that changing the value of R19 from 2. Which consequences would this modify has on the circuit? Maybe a 22 ohm You shouldn't have to mess with the gain of the amp to get this to go away. My only concern from ealier posts was that running this board without the remote resistor might be feeding too much gain into the amp but you said you tested other boards this way and the gain wasn't too high in those cases.

I wouldn't replace C12 unless it is for a test. You can safely test this with a 1uf electrolytic. That is what system 6 boards use for coupling capacitors. I would hang on the the tantalum cap and put it back in if the 1uf doesn't solve the problem.

The fact that the buzz is reduced when the cap is removed suggests that the buzz is being introduced before the amp stage. I also tested the board and the remote pot doesn't solve the problem. The disturbe comes from the speaker. Here another video where I test a working board. You can listen than the sound is completely different. Could you explain me how to do it? You have it right. Basically what you are doing is measuring how much ripple voltage is making it past the power supply filter caps on all voltages and voltage regulator on the 5v supply only.

What is the meaning of this "test"? The bridge rectifier is new.. I've already change it, but before making short. I can change it another time, no problem! Thanks, as usual!!! Are you sure about the range of those AC measurements? Are you sure the meter wasn't reading millivolts? As in. You should see less than. I don't know.. On the screen no dots for millivolts but the values of

Audio Amplifier Modifications

This article now combines information for all these chips - you may been redirected here from the TDA article. Warning: These chips have all been discontinued and are susceptible to fakes. If you're buying, make sure it is from a good supplier i. Recommended Experience : lower intermediate, knowledge of amplifiers, PCB etching, heatsink attaching, and optional mains qualification. All of these chips are 5 pin Pentawatt TO similar devices that basically operate in the same circuit, with minor differences in component values.

R1 is not included in mine as it doesn't make a lot of difference and produces noise when I try to adjust the volume. How can this be solved? Above a certain volume set in the music player, the 8 ohm, 3 inch diameter speaker gives out distorted sound. How can I avoid this? If the 3. How is this noise produced and how can it be removed?
