Good evening,
I recently came into possession of a pair of Mark Levinson 33H power amps, which are quite battered. The restoration and restoration process has almost reached its end, but it is not clear what the correct calibration values for the bias and power supply voltage of the preamplifier boards are. I am not even able to establish the settings of the oscillator board.
Does anyone have the service manual? Or do you know who to contact to get it (for a fee of course). Here in Italy it seems impossible even through the official importer.
Thanks to anyone who can help me

Thanks! But we need the bias value(mV) and the volt output regulator of voltage amp.
If possible... The schematic of input and voltage amplifier.
There is no circuit diagram for NO.33H, the circuit diagram for OSC-33 is different from that for NO.33H.
