# 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.
Vacuum Tube - 50A5, Tetrode, Beam Power
Beam power amplifier designed primarily for use in the output stage of a-c/d-c receivers. The 50A5 features high power sensitivity and high efficiency when operated at relatively low plate and screen voltages.
$4.90 Vacuum Tube - 5755 / 420A, Dual Triode The 420A electron tube is a double-triode having separate indirectly heated cathodes. The heater is center-tapped to permit operation from a 6.3 or 12.6 volt filament supply.$4.95
