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 - 10BQ5, Beam Power Amplifier, output pentode
The 10BQ5 is an output pentode designed for application in medium power hi-fi amplifiers. A pair of tubes in class AB, push-pull conventional operation yields an output of up to 17 watts at 4% distortion (without feedback).
