Ampere Audio 8k

When I measure the voltage of the squarewave off of the 494 chip pin 9 is a 6v wave and pin 10 only has a 4v wave. What would cause this. Ive tried 2 different chips and they both do it.

The loading on the output by the drive circuit.

I put all new follower/emitter pairs in and there isn't any mosfets in. What could be loading it?

also it draws .1 amps when the pos and neg are hooked up with no remote.

Was there any thermal damage to the board near the drivers?

Is the DC voltage on terminals 8 and 11 the same?

It's possible that there is a problem with the current draw with no remote but some amps do draw current at all times.

Post a photo of the component side of the entire main board and the component side of any driver boards.

There was thermal damage but not by the drivers.
