    Technics SA-828 - Static with audio, then stopped working

    I tried to put the schematics all on one page which works okay but the scans were missing some areas so I couldn't match them up perfectly. But at least I don't have to keep swapping them out so much. It's 4 meg so I couldn't upload it. If you want to take a look, I could email it to you...send...

    Technics SA-828 - Static with audio, then stopped working

    Right I rechecked each individual diode forward and reverse and read roughly.485 forward and ol reverse so I assume the rectifier is working properly. I also checked Q703, Q704, Q708, Q711 and they all check good.

    Okay, yes I did check all around and I read .5 and .9 respectively.

    As for those TQ-220's Don't forget, I have a 50% chance of putting them back the way they were. : )

    Correct no power good relay and when the right channel did work, it was distorted. On the rectifier, I held the negative lead on the notched end and positive moving clockwise, I got .507, .911, .484 We can bias the output, that shouldn't be a problem

    Technics SA-828 - Static with audio, then stopped working

    I was testing resistors last night and I came across R689, R690. Both are 10^ 1W but I was measuring 0.000 on both of them. There are a couple other 10^ resistors there too and they measure fine. Does the coil L601, L602 beside R689 and R690 have an effect on the readings I'm getting for those...

    Technics SA-828 - Static with audio, then stopped working

    The stereo did work for a while with the one channel good and the other one sounding distorted and then the relay quit switching on altogether I have not removed the output transistors from the heatsinks so they can only go back in where thay came from. Everything tested good ... NPN ---...

    Technics SA-828 - Static with audio, then stopped working

    Hey Guys! I've been following along because I have an SA-828 too. It used to work fine and then one day I turned it on and the right side was all static mixed in with intermittent audio. Then it stopped coming on at all. : ( I'm sending along a few photos to show where I am so far, (with your...
