I can’t seem to find out where the ground is broken to pin 15 I’ve checked pretty much everything .
Do you have a schematic for this amp ?
PC-3125-F
Or do you know what board locations are the pnp drovers for the power supply ?
Since they do not go to ground either so somewhere I have a break in the ground and wanna track down the issue .
The collector of the pnp drivers should connect to amps ground terminal but they aren’t

From pins 6,7,15 of the 3526 to amps ground terminal I should get something like 0.4 ohms correct ?
Right now I’m getting 2k ohms

Ok I found the break in the ground connection to pond 6,715 fixed the connection
The pnp drivers should also be directly connected to ground amp correct ?

Ok I found the issues and fixed the solder connections I will put new drivers in the amp and the fets back in and see what I come up with
Power supply is working correctly now .
Next problem I have is Q15 and Q16 regulators get to hot to touch within 10 secs of powering the amp up .
