Technics SA-5470 - DC Voltage @ Left Output

[Lui]

Hello everyone!
I'm fairly new to this forum and to vintage equipment in general. I have a Technics SA-5470 with a brand new set of power and driver transistors. I also changed a a few bad resistors and one other transistor. Someone had shorted out the left channel on this unit.
I was originally using another thread on this forum as a guide to fix this, and that got me very far. However, once I powered the unit up and looked at the DC Voltage on the speaker terminals, I noticed I had around -50mv on the left channel and almost 0mv on the right. I'm not sure what to do now or what other parts to check. I've looked around but nothing really catches my eye as being out of place.
Do you guys have any suggestions as to what I should do now?

Thanks.

50mv is not that bad. Not even enough to trigger the protect circuit. However you could reduce it by replacing the input differential pair (TR601) with a new match pair of KSA992FBTA

Awesome! Thank you very much for the suggestion. I really do hope that helps. I didn't even think of checking that transistor.
I actually did hook up a pair of speakers and I can hear a bit of hiss/hum coming from the left speaker, but also slightly from the right :'^<

Yesterday I actually did swap those transistors around and the issue did move from the left channel over to the right. Thank you for the suggestion! I've already made the order and it's just a matter of time before I can completely fix my unit. Thank you!
