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 - ECC99, JJ Electronics
The JJ Electronic ECC99 is a noval based dual triode. This tube features a rugged construction and is also available with gold pins. The ECC99 is typically used as a driver for power triodes in 2A3 and 300B amplifiers but can also be used as a power tube in small amps and headphone amps. This tube can also be a functional replacement for 5687, E182CC, 6840, and 6BL7 tubes. Note: Sockets on some of these types could have a different set-up.

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.
