Let me see if I understand you about the DRD amp: 1. The filament on the 300B is driven with DC. It comes from a transformer winding that is rectified and filtered. 2. The driver tube heaters are driven with AC that comes from a different transformer winding than the 300B filament supply. Is that right? Do you happen to know the filament voltages for each tube? Do you know the plate voltages? Is there a single rectifier for B+ for all tubes?
