Hey folks, I recently acquired a pair of MC30s off of this great site! I'm going to restore them, and I understand there is the "Hints & Kinks" thread, but I'm trying to consolidate to one thread because I'm very new to this. The first question I have is in regards to the schematic. Both amps have A-152-D and A-150-C transformers. The only clear schematics I can find is the A-152-B schematic. Can anyone help with this? I assume I can't use that schematic. Serial numbers are in the 150xxxx range.
