For the time being, I’m using an 814 (triode-strapped) single ended amplifier with the following key features:

  • 100% DHT – drivers and output valves
  • 12W output power @ THD=1%
  • DC coupled
  • Output valves: 814 triode strapped
  • Rod Coleman regulators
  • 46 (triode-strapped) driver with filament bias
  • Filament and HT supplies LCLC

  • Rod Coleman filament regulators
  • Filament bias
