Adcom GFA-535 Settings

[Ardvaark]

I've picked up a working Adcom GFA-535 amplifier. It seems to have two issues where I need assistance. The dc offset in the left channel measures 24mv while the right channel measures 37mv. I need help in where to check for bias and how to possibly adjust both the dc offset and bias. Also I've noticed after two hours the right side of the unit gets about 60% warmer than the left side.

Thank you,
Ardvaark

The right side has a higher dc bias so is sinking more current.

However, those dc biases are pretty tiny, I personally wouldnt worry about them.

If it is affecting the quality of the sound or the equal playback of the music to any degree, then I am worried about it.
