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 - 12DW7 / ECC832, JJ Electronics, Dual Triode
In the 12DW7/ECC832, Section 1 of the tube (pins 6, 7, and 8) is the high gain 12AX7/ECC83 spec (gain factor 100) and Section 2 (pins 1, 2, and 3) is the low gain 12AU7/ECC82 spec (gain factor 17).

Vacuum Tube - 12AX7 / ECC83-WA, Tube Amp Doctor, Premium Selected
The new Tube Amp Doctor premium selected 12AX7 /ECC83-WA is a low-noise and low microphonic version of the 12AX7. The ECC83-WA Premium Selected has a balanced tone with a notable emphasis of the mids. The overall linear sound offers great string attack and chord separation. The low end is well defined. The result is a tone that works well in both modern amps but also vintage guitar amplifiers. If the ECC83-WA is used in hi-fi audio amplifiers, the tube adds a musical clarity and presence to the signal. The new TAD™ ECC83-WA is a miniature, high-mu twin triode, selected and recommended for guitar amps to improve overall responsiveness and dynamics. Great for guitar clean tones with a distinct pick attack and pronounced upper mids to cut through every mix. Crunchy tones still feature a very good string separation which is also ideal for fully saturated sounds and modern amplifiers with a tight bass response.
