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.
Sharp cut-off general purpose amplifier. With the exception of heater and capacitance ratings, the electrical characteristics are similar to those of the 6C6.

Electro-Harmonix 6CA7 Vacuum Tube Big bottle beam-tetrode version of EL34. Perfect EL34 replacement for Musicman amplifiers.
Starting at $36.10
The TAD 6L6GCM-STR REDBASE is Tube Amp Doctor's latest 6L6GC; designed and built to be the best 6L6 type tube ever manufactured. A high claim, but Tube Amp Doctor is sure that they have achieved exactly that. In terms of sound, the TAD 6L6GCM-STR REDBASE produces the powerful but always defined bass response known from the legendary american built NOS RCA 6L6GC, with clear, unobtrusive and yet transparent highs.
Starting at $35.95
Miniature sharp-cutoff pentode. Its high transconductance and low input and output capacitance adapt it to use as a wide-band amplifier or as a reactance tube.
$3.55
Metal sharp-cutoff pentode designed for use as a biased detector or high-gain amplifier.
$6.90
Genalex Gold Lion ECC81/B739 (12AT7) dual triode preamp tube with gold pins. Made in Russia. Original Genalex Gold Lion ECC81/B739 tubes are considered the best 12AT7 types ever made. They are also among the rarest types available. They exhibit a large detailed soundstage that is characterized by an expressive midrange, deep tight bass, and a smooth extended high end. The reissue Genalex Gold Lion ECC81/B739 recreates the sound signature of the original. This tube features balanced sections and gold plated pins.
$62.35
Combines two independent diodes in the lock-in construction permitting the tube to be used as a power rectifier in either half-wave, full-wave, or voltage doubler applications.
$4.90
High-perveance beam power pentode designed for use as a horizontal deflection amplifier tube in high efficiency deflection circuits of television receivers.
