I am trying to revive a Luxman L-11. This amp hasn't been used in years and needs the DC Offset adjusted and I am sure that the BIAS will require this as well. If anyone has any information on this or has a service manual that they can either share or sell, I would be most grateful. I have found the schematics for this amplifier but there in nothing there that helps with the adjustment of the offset or BIAS.
Thank you all.
Thank you all.
Attached is only info I could find, probably what you already have.
You probably know the following: Output offset can be trimmed via VR501 and bias current by VR502. Bias currents would be sensed across the 0.22 Ohm resistors.

I am grateful for your assistance. I appears that there is very little on this amp. Any idea as to how much current the BIAS is to set at ?
