Vacuum Tubes

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.

New Old Stock (NOS)

Our new-old-stock tubes were made in the U.S. by the major manufacturers, with several types made in Western Europe or Japan. All NOS tubes are tested and guaranteed.
T-4D32 Vacuum Tube - 4D32, Tetrode, Beam Power
Beam type aligned grid power amplifier. It has a unipotential oxide-coated cathode, a hard glass nonex bulb, and a glass base with short tungsten leads. The tube has a heater designed to operate from a 6.3 volt supply.

SET-TV7-CALIBRATION Vacuum Tube Set - for calibrating TV-7 Testers
This is a set of measured vacuum tubes for use in TV-7 vacuum tube tester calibration. The values for each vacuum tube will be measured and included for the purpose of calibrating your own TV-7 tester at home. Steps for this calibration can be found online. Three tubes will be included:
  • 6L6
  • 6AU6
  • 12AT7

These tubes are tested at the following settings: Tube Filament Settings Bias Shunt Range 6L6 6.3 HS5-3481 23 0 D Tube Filament Settings Bias Shunt Range 6AU6 6.3 ET1-5672 16 0 B Tube Filament Settings Bias Shunt Range 12AT7 12.6 EV7-6080 10 0 C Note that brands are not guaranteed to match photograph.
