The first electronic amplification of sound was done with Vacuum Tubes. We have pre-amp, power and rectifier vacuum tubes among other types in New Old Stock from the golden era of American & European manufacturing as well as current production tubes from today.
Vacuum Tube - GZ34 / 5AR4, Mullard Reissue
Premium directly heated heavy duty rectifier Diode. Re-issue of the most popular rectifier valve ever built by Mullard. Helps extend the life of the other valves in the amplifier by allowing them to heat up before plate voltage is applied.
- Low internal voltage drop & controlled heater warm up time
- Excellent choice for both Hifi and instrument amplification
- Replacement/upgrade for all 5AR4/GZ34 types
