Danno25, The bias adjustment is important. If improperly set you will get either excessive heat or excessive crossover distortion, especially at low power.
Many SS amps have a bias and a DC Offset control. I would start with the DC Offset- the amp should read 0.00V at the speaker terminals. Its likely that you will not be able to actually hit that reading due to noise. But you should be able to get it so that it drifts back and forth across 0Volts.
If you don't have an audio oscillator, you can use the DC Voltmeter to read the voltage drops across the emitter resistors of the good channel. Although they too may have drifted over time, if that channel has been behaving OK (heat and sound is nominal), the bias may be set fairly close to correct. You could then duplicate those readings in the repaired channel.
Be careful with the meter probes! You don't want to have to replace parts again... -good luck!
