How to do Output adjustment for Sansui 4000 without oscilloscope
You cannot set the offset bias adjustment on the Sansui 4000 by measuring the voltage on the output capacitor while idling. The offset pots VR801 and 802 will not change the DC voltage on the output capacitors. Those two pots are capacitor coupled into the circuit, so they cannot effect the DC offset (look at the schematic).
