I am planning on adjusting the driver and final bias on my Orion II, which is
something I have never done. I assume that the correct way to do it is by
inserting an ammeter in the B+ to each of the two drivers (Q1, Q2) and to the
pair of finals (Q3, Q4) and adjusting for the current shown on the schematic.
Would that be the correct way to proceed?
The last time it was at the factory, they found the bias out of adjustment and
one of the pots bad.
Thanks,
Ron Castro
