writes Corrected schematic to show actual wiring of heater string. First 12AT6 preamp heater is closest to ground. [ A MIME image / gif part was included here. ] This arrangement might also help with reliability. The heater-cathode breakdown rating of a 12AT6 might not be as high as a 50C5 (but I haven't checked). -- Ian |
