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.
T-12AX7-CZ-PS-TAD Vacuum Tube - 12AX7 / ECC83-Cz, Tube Amp Doctor, Premium Selected
The Tube Amp Doctor premium selected 12AX7 / ECC83-Cz features big, warm, clean sounds with a mellow top-end when pushed to overdrive. It’s a great choice for guitar amps and HiFi alike. The ECC83-Cz is recommended if you want to emphasize punchy mids and is especially great when pushed into a fat overdrive. The TAD™ ECC83-Cz is a miniature, high-mu twin triode with good gain, round deep bass, somewhat compressed mids and very smooth top end. Selected and recommended for guitar amps to smoothen up the tone or for HiFi to shape the body of sound more to “that” tube tone. Best for jazzy and thick clean as well as for vintage bass response. Recommended for all positions in amps with medium gain level or High-Gain Amps for V2+ positions. As for V1 in general but especially for higher gain amps or phono/audio-amps, we recommend the RT030 7025/E83CC Highgrade, T-7025-HG-TAD.

T-6V6GT-RB-TAD Vacuum Tube - 6V6GT-STR, Redbase, Tube Amp Doctor
The TAD 6V6GT-STR Redbase combines the tonal characteristics of an NOS 6V6GT such as from RCA or GE with the current requirements. It is a heavy duty 6V6GT tube, which can handle a higher plate voltage than regular 6V6GT tubes. The TAD 6V6GT-STR Redbase shines with the typical NOS "sweet top end" and at the same time a strikingly dense and complex midrange. Especially with this midrange characteristic they achieve a liveliness in tone that only NOS 6V6GT achieve and otherwise remains unmatched. Even when pushed into saturation there are no harsh upper mids, which is frequently the case with other 6V6s. Sweet full-bodied tone with silky highs. Tube Amp Doctor recommends the TAD 6V6GT-STR Redbase for all 6V6 power amps when a full yet freely defined tone is desired. The ideal tube for Fender Deluxe Tweed 5E3 or Blackface Princeton Reverb amps, single ended Class A amps like the Fender Tweed Champ, Vibro Champ, Fender Champion 600 or the Univalve.
