Realistic SCR-8 Main board

[Lost&Found]

I have a SCR-8 with a non working channel, Have replaced the amp chip and will keep seeing if I can find the issue, but if someone has a working main board it would make this simpler. I've seen 2 versions of component connectors in these boxes, Brown and White. This box has white connectors.

Try the Potentiometer (Volume). These can be taken apart and cleaned.

Thanks for the advice @hopey . I did use deoxit on all the pots, though I’ve just found a thread where it’s discussed that it’s not a good way to clean them. The amp chip that replace seems to get hotter than it should. I haven’t left it on long enough to see if it starts cutting out but it gives me the impression that there’s a bigger problem. Maybe a short somewhere. And I really don’t have the knowledge to trace it down.

It's still worth opening up the the pots you maybe able to leave them attached to the PCB.
