RE: 6V6 Amp Feedback....Start Over Please
Posted by sony6060 on January 1, 2017 at 11:57:34:
Back to original question. I am now using one section of 6CG7 to drive 6CG7 phase invertor as shown in first schematic. First section 6CG7 tube uses 50K plate resistors, 1.2K cathode resistor (no by pass capacitor) with 180 volt plate voltage.
What feedback circuit parts would you use in PPP tetrode from either 8 or 16 ohm audio transformer secondary?
