    Technics SA-410 No audio from right channel

    Hi, I have a Technics SA-410. When it's cold and I turn it on, the left channel works fine. The right channel is silent until I turn it up to around 3 and then it comes on and stays on and works fine. I can turn it off and on and it will stay on once it's warmed up. What do you think the...

    Technics SA-828 Receiver from 70s- Is it worth trying to save this aging patient?

    Hi! How have you been? Sorry it took so long to get back but you know how life can get in the way of things you'd much rather be doing lol. Well, I got the receiver working again and I've had it powered up several hours, several times, without fail. One thing I have noticed is that Q708, which...

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

    Yeah, very weird. At first, when the relay first came on, I went to plug in a speaker on the left side and I saw a spark. So, obviously I didn't do that again lol

    The right side had - 62 v dc and the left side had + 62 v dc Enabling or disabling the speakers had no effect at all. What do you make of that???

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

    while I was probing around there with the stereo on, it suddenly came out of protection mode. But it wasn't good out of the speaker terminals. Basically, it squealed and cut back into protect again. When I cut the speaker output off at the front panel, it came out of protect mode again. The...

    Hi, I measured d1001 and got anode 38.43 and cathode 39.75 Pin 8 on IC1002 was -26.8 mV Z601 0 V Z602 -63.8 V R1049 148.7 C1009 37uf The amp is definitely in protection mode and yes, the red light is lit for safety. The display appears to be working fine.

    Hi, 73s best regards. Have you had a chance to look at the voltages I listed above? If so, are they out of whack or what would be the next step to home in on why I have no output?

    All back together! Same result as before : ( I expected that though because I didn't find anything wrong. At least I know all those transistors are good. The display seems to be fine. What do you think?
