Hi, Rico!
If we should help you, we need more information. Did you buy the amp or is it a homebrew model? Which schematic do you have? What do you want to do? We can't give you a "mod-manual", if we don't know what's up!!

PLAY LOUD!!

P.S.: Did you ever solder before?

I have the schematic that is available on the Internet in *.pdf files, they are: 1BLK_DIA.PDF
2PWR.PDF
3PRE_PT1.PDF
4PRE_PT2.PDF
5PRE_PT3.PDF
6PWRAMP.PDF
NOTE.PDF
SWTCH_P1.PDF
VOICE_23.PDF

There u can see the LM394 chip. Maybe some parts of the schematic are missing, maybe not, but i can not see where should i connect this chip and some more traces, that i was asking about in "Need help - tracing PCB - dual rectifier 3-channel " here in this forum.

So, i need help on this questions.
