[tamtamstudio]

Hi all, I've got a problem with my  ev8b KRK studio monitor.
1 amp inside one of them make some noise, crackle..
I've got in my hand and i found +4VDC on final stage, that's not good..
Anybody have got the schematics for this amp?
Before i try to draw the schematics.
Any suggest is welcome.

I may have a schematic for the older V8  model.

In the beginning that's what I tough, I resoldered all the board, no success.
Now I'm trying to reverse schematic, hope to find something bad.

Sorry about the slow response, been very busy and also working while having the flu.

The schematic is hard copy and I have nothing on hand to scan it,but I'll give you some info so you can check the parts against your amps.
