Superscope r330b dc offset

[hifiaudio1]

I just got a Superscope r-330b receiver and the dc is a little high in one channel and has a turn on thump on both. I do not see any trim pots on the amp board and there is no info it. How can I lower the dc on it.
Thanks in advance

Can you take some pics of the power amp board? Maybe we can help you out with it.

Heres a hack you can do to get rid of the turn on thump.
1/ Turn the speakers off at the amp.
2/ Turn on the amp.
3/ Wait a few+ seconds for the caps to charge and settle.
4/ Turn on the speakers at the amp.
You've just done the work of a relay.
This is just a hack, and if you want it right you'll have to recap.
