Acc. to the sch C4 is 220uF/25V and is filtering B4....
OK, on the top level C4 is what you said....
Well, as I said, you do not have DC loads there,
so if when attaching either L or R amp with no load you draw large current you then should look for either a short or a bad part in the amp.
There are switches connecting headphones and such....
When amp is connected, is its output disconnected from everything?
You need to connect ONLY B1 power but nothing else should be connected to the power amp. Only Power, that is B1 and E.
And make sure E1 - E4 are all connected.
