# 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.

Vacuum Tube - 1L6, Heptode
Miniature type pentagrid converter designed for use in low drain battery operated receivers.
Starting at $40.65 Partially Out of Stock Vacuum Tube - 6J8G, Triode, Heptode Converter tube designed for stable operation over an extended frequency range. It consists of a heptode mixer and a triode oscillator, having a common cathode. The injector grid of the heptode is internally connected to the triode grid.$18.90
Vacuum Tube - 1LA6, Heptode
Low-voltage, low-current drain battery type pentagrid converter. It is designed for service as an oscillator and mixer in superheterodyne receivers which require only 90 volts of "B" battery and a single dry cell "A" battery.
$11.90 Vacuum Tube - 6BA7, Heptode Cathode type high gain pentagrid converter in the small 9 pin button construction. It is designed for service as a combined local oscillator and mixer at high frequencies, especially in the FM broadcast band.$9.90
Vacuum Tube - 12SA7, Heptode
Pentagrid converter designed to minimize frequency drift. They are intended for service as combined oscillators and mixers in AC, storage battery, and AC/DC operated superheterodynes.
$8.90 Vacuum Tube - 6AJ8 / ECH81, Triode, Heptode Triode-heptode for use in F.M., AM/FM, A.M, and television receivers.$8.90
Vacuum Tube - 12BE6 / HK90, Heptode
Miniature pentagrid converter designed to perform simultaneously the combined functions of the mixer and oscillator in superheterodyne receivers. The tube is suitable for use in the standard broadcast and FM bands.
$7.90 Vacuum Tube - 6BE6 / EK90, Heptode Miniature heptode primarily designed to perform the combined functions of the mixer and oscillator in superheterodyne circuits in both the standard broadcast and FM bands.$6.90
Vacuum Tube - 14Q7, Heptode
Pentagrid converter designed for use as a combined oscillator and mixer in superheterodyne receiver. The electrical characteristics of the 14Q7 are similar to those of the 12SA7
$5.90 Vacuum Tube - 1R5 / DK91, Heptode Miniature pentagrid-converter designed for use as a combined mixer and oscillator in superheterodyne circuits. Because of its small size and high operating efficiency, the 1R5 is especially adapted for compact, battery-operated equipment.$5.90
Vacuum Tube - 6L7, Heptode
Mixer tube designed for service with a separate oscillator as the first detector in superheterodyne receivers. The control grid is of the remote cut-off type which allows the use of AVC and minimizes cross-modulation.
$5.90 Vacuum Tube - 1LC6, Heptode Filament-type pentagrid converter designed particularly for use in low drain battery-operated equipment. This tube will operate satisfactorily with only 45 volts B supply.$4.90
Vacuum Tube - 5750 / 6BE6W, Heptode
Miniature pentagrid converter designed for use as a combined mixer and oscillator in superheterodyne circuits.
$4.90 Vacuum Tube - 12AD6 / 12AG6, Heptode Miniature heptode primarily intended to perform the combined functions of mixer and oscillator in automobile radio receivers. Specially designed to operate with plate and screen voltages supplied directly from a 12-volt storage battery.$3.90
Vacuum Tube - 6SA7, Heptode
Metal pentagrid converter. It is intended to perform the combined functions of the mixer and oscillator in superheterodyne receivers, especially those of the all-wave type. The 6SA7 is constructed to provide excellent frequency stability.
$3.90 Vacuum Tube - 6BY6, Heptode Miniature dual-control heptode designed primarily for use as a combined sync separator and sync clipper in television receivers. Each of the two independent control grids exhibits a sharp cutoff characteristic.$2.95
Save 50%
Originally: $5.90 Vacuum Tube - 6CS6 / EH90, Heptode Miniature dual control pentagrid tube intended for use in sync separator circuits. In these circuits it provides improved noise immunity. Both control grids have sharp cut-off characteristics.$2.45
Save 50%
Originally: $4.90 Vacuum Tube - 7B8, Heptode Pentagrid converter designed to perform the combined functions of the oscillator and mixer in superheterodyne receivers$1.95
