Do the tubes operate at true amplifer plate voltages?
Yes, the tubes operate at 300 Volts D.C. Our high voltage power supplies are fully regulated and smoothed to ensure low noise. Many other manufacturers of tube pedals are operating tubes at voltages as low as 12 volts. I guess this is for economic reasons or for lack of ability in power supply design. It’s certainly not for better tonal quality because low voltage operation (current starvation) of tubes sounds terrible. To avoid an electrifying experience, refer servicing to qualified personnel only. High D.C. voltages of up to 400 volts are present in the circuit. Whilst working on the power supply design for these pedals, I’ve experienced an electric shock or two and it’s not a pleasant experience. Beware!
