Luxman R800 bias adjustments not in service manual

Solid State | Audiokarma Home Audio Stereo Discussion Forums - audiokarma.org
Hi,

I'm trying to find out how to adjust the bias of a Luxman R800.

I replaced all electrolytics and it works great.

But it had 100mV on one speaker which I put down to about 0.

There's still one variable resistor (VR702) to adjust and I have no idea how to do that. Should I set it to 0mV through R726 (0.39 oms) ? One output board reads 0mV through it, the other 4.4mV.

Thanks !
