Today the Tone Priest does the unthinkable; he listens to the Tone Nun, pulls into a gas station and asks for directions.

The troubleshooting so far:

- Tetradruple checked all wiring & components against schematic & layout
- Checked all voltages
- Checked proper function of negative bias voltage
- Tried various tubes in all positions & using known good tubes
- Added 470k grid stopper into cathodyne phase inverter
- Swapped output transformer primary leads before & after adding grid stopper
- Tried with the negative feedback disconnected

Main suspects:

- Blocking distortion from the ninth plane of hell
- Tube oscillation from the sixth plane of hell
- Chocolate in my peanut butter

This and all Tone Priest videos are for edu-tainment purposes only. Guitar amplifiers can have lethal voltages in excess of 700 volts. Capacitors can retain a deadly charge even when an amplifier is turned off and unplugged. Videos are not instructional nor do they advocate anyone doing any kind of repairs on their gear. Nobody should do electrical work on anything for any reason ever. Keep your hands and belongings inside the car at all times.
