Hi, just found one of these amps, somebody knows the bias current adjustment for this baby?, any help, schematics or service manual will be appreciated.

Thanks, Reon

Reon I have one I am also looking for a manual. However. One channel on mine has a sticker from factory with a bias of 26ma idle and 76ma operate. The other channel has 16ma idle and 66ma operate. I have installed 2 rectifier bridges and 4 cerafines to make more dual mono.

I have a hand drawn schematic for this amp. I didn't draw it so don't know how accurate it is. PM me if you want it.
