Hello, could someone help me? I have bought an accuphase p300 amplifier and the 1s2091 and Cz057 diodes are missing on the power board and I can't get them, someone could help me
1. I don't see such diodes on the schematic which is no surprise as production parts are often altered. Can you specify the schematic designators, like D1...
2. Whatever they are it will be trivial to replace them, so no worries on this account.
3. Missing diodes is an almost certain indicator there is a lot more wrong with the amp. Thread cautiously.
It's probably just my eyes, spotted the 1s2091 in a few locations. You can use anything there, even 1N4004. Maybe even a 4148 will be fine but please specify the location.
