I would like to perform basic operational checks and adjustments on a DC-300A Series II amp. Things like DC offset, bias, etc. A schematic would be most helpful as well.
1. I noticed there is very complete service documentation available for the D-150A Series II. Is a service manual available for download or purchase for the DC-300A Series II?
2. If #1 is not possible could someone kindly provide a brief description of values, test points, and components to adjust for DC offset, bias, etc.?
