Anyone know what transistors usually fail on this driverboard??
They all test good but as soon as i install it in the amp the amp will start drawing excessive current..
Outputs are brand new so i know thats not an issue also everything on the main board tests fine..

Replaced all the drivers on the audio driver board..
Amp is up and running flawless..
Thanks for posting your fix.
got this amp back with a blown power supply..
replaced the power supply fets now i have a strange issue with it..
Theres is 1.22 volts meaured directly across the speaker terminals..
If i wiggle the RCA jacks around the voltage on the speaker terminals pulse's i can get all the way up to 16 volts the it drops back down to 1.22 volts by wiggeling the rca jacks.. Any ideas?

Yeah you car correct..
Between RCA input shields and negative speaker terminal i get 218 ohms so R100 is within tolorance..
I found a broken ground on the rca jacks fixd it..
Now i still get -2.57 volts on the speaker terminals..
Any ideas where to begin to start looking ?
