Repairing the Carlsbro powerline pro 2000 amp

[electronicsman]

Hy,
I am curently repairing a carlsbro powerline pro 2000 PA amp.
The problem is, that the left channel of it distords hardly.
I checked te preamp and input board and they are fine(I swaped the channels)
The issue is not in the main board, but it is in the driver board.I replaced all of the transistors on there, but it stil does not work.

If anybody has the schematic of this amp, I would realy apreciate if you post it!
Thanks, thousand times.

I have got one which i bought as a backup, they are pretty good amps. Problem i had was the output speakon connectors. chinese crap. Mine continually distorted on one channel,so what i did rather than replace new speakon sockets,which is a big job was to wire new speakon sockets from the binding posts. Job Done.

I've repaired a few of these and its always been open circuit resistors. If one channel is working it should be fairly easy to compare voltages and find the area causing grief.

Thanks for all the help!
I really appriciate it.
I will try to measure and compare the voltages from the other channel. I already checked the binding posts and speacon connectors, they are ok!

Thanks, good day everyone!
