Vacuum Tube - 6CB5A, Beam Power Amplifier
High perveance beam power pentode in a T-12 glass envelope. It is designed especially for use as a horizontal-deflection amplifier in color television receivers. The 6CB5A is unilaterally interchangeable with the 6CB5.
$29.90 Vacuum Tube - 6CK4, Triode Low-mu triode designed for use as the vertical deflection amplifier in television receivers.$12.90
Vacuum Tube - 6DZ7, Dual Pentode, Power
Twin power pentode designed for use in the output stage of high-fidelity audio amplifiers. The incorporation of two pentode sections in one envelope makes it especially suitable for compact stereo systems.
$33.90 Vacuum Tube - 6E5, Indicator, ST Shape Glass High-vacuum, heater-cathode type of tube designed to indicate visually the effect of change in the controlling voltage. Essentially a voltage indicator and as such is particularly useful to facilitate exact tuning of a radio receiver.$39.90
Vacuum Tube - 6F5G, Triode, HI MU
Triode, high mu
$29.90 Out of Stock Vacuum Tube - 6FH5, Triode, HF Neutrode triode tuner in the 7 pin miniature construction. It is designed for use in grounded cathode RF amplifiers, with the neutrode construction providing a lower grid to plate capacitance with consequent ease of neutralization.$2.95
