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 - 6H30PI, Electro-Harmonix, Gold Pin
Sovtek 6H30PI dual triode preamp tube with gold pins. Made in Russia. The 6H30 is a medium-mu dual triode with a very high-perveance cathode. The low plate resistance, combined with a superior linearity, and a true 4 watt per plate dissipation, make for a high performance voltage amp or driver.

Vacuum Tube - 6550, JJ Electronics
The JJ Electronic 6550 is a robust tube built in the rugged fashion that JJ is famous for. At 35 Watts, these tubes have a warm round tone with a thick and defined low end. The JJ 6550 is an excellent choice for bass heads, tube organs, and Hi-Fi amplifiers.

Vacuum Tube - KT66, Tube Amp Doctor, Premium Selected
The Tube Amp Doctor KT-66 is an incredible remake of the classic British tube. With its large glass envelope contoured by smooth curves tapering into a rounded brown base, the TAD KT-66 not only looks like the original, it performs like the original. This KT66 offers plenty of headroom for a thick full bodied sound with smooth yet articulate highs. The KT-66 is famously used in vintage British plexi amps and makes a great replacement for that style of amplifier and many others. The TAD KT66 is matched for both plate current and transconductance and passes all of the tests of the TAD Premium Selection process. The TAD KT-66 can be used in any KT-66 position as well as 6L6GC and 5881 amps that can supply the required 1.27A for the heater.
