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.
Heater-cathode type full-wave high-vacuum rectifier doubler tube designed for use in the power supply of a-c or a-c/d-c receivers. Eletrically the 25Z5, 25Z6, and 25Z6GT are identical.
Filament type triode designed for use in the amplifier stages of a-c operated receivers.
R-F amplifier pentode, miniature remote-cutoff type, for use with 12-cell storage battery supply.
Glass octal type used as horizontal-deflection amplifier in color television receivers.
Compactron beam-power pentode primarily designed for use as the horizontal-deflection amplifier in color television receivers. It is characterized by having a very low knee with a very high peak current of over an ampere.
Ruggedized heater-cathode type double diode using the 9 pin miniature construction. It is suitable for use in half or full wave rectifier applications or as a voltage doubler.
Three-electrode general purpose tube of the heater-cathode type for use as an amplifier and detector in a-c receivers.
