# 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 - 407A, Dual Triode, Medium MU
9-pin miniature double triode with separate indirectly heated cathodes. It is designed for use in amplifier, mixer, oscillator, multivibrator and clamp circuits. The useful frequency range extends through the VHF range.
$9.95 Vacuum Tube - 417A, Western Electric, Triode 9-pin miniature triode with an indirectly heated cathode. It is intended primarily for grounded-grid operation in the input stage of broad band amplifiers.$174.90
72.90 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.71.95
