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.
Tube Amp Doctor (TAD)TAD is a German company established in 1993 which selects and matches electronic tubes and manufactures musical instrument accessories.
New Old Stock (NOS)Our new-old-stock tubes were made by the major U.S. manufacturers, along with a small number of European manufacturers and are tested and guaranteed.

9 pin miniature preamp tube (Amplification Factor =100). Very good gain, tight deep bass, fat mids and silky top end with overall definition and brightness. Selected with balanced systems and recommended for guitar amps to improve overall response.
The TAD 7025 WA delivers full gain with smooth top end. No microphonic issues even with the most sensitive preamps. The 7025 WA supports a fat midrange and creates a bold tone with lots of overtones. Played clean the TAD 7025 WA delivers a warm liquid tone which is very responsive to dynamic playing. Overdriven the 7025 WA provides lots of sustain with well defined mid-range punch.
Rich-sounding Reverb Driver - Also Great for Headphone Amps! Low noise tube, selected for best symmetry and balance. A strong driver tube and a wounderfully rich-sounding reverb driver.
Maximum of Reliability - Outstanding Tonal Quality! The all-new TAD 12BH7A-STR combines the best sonic and mechanical performance of the NOS RCA black plate with advantages of the GE version.
The TAD ECC83 WA Selected provides a stunning warm tone, thick midrange and sweet natural harmonics. We designed it with a triple mica construction for low noise performance. Perfect for clean or moderate gain preamps as well as for high-gain amps from V2 position. Its great dynamics, low noise operation and balanced warm tone make the TAD ECC83 WA to be an excellent all-rounder with great value for money.
Combines two diode units and a high-mu triode in a single envelope. Each section uses a common cathode. It is intended for service as a combined detector, AVC source, and high gain audio amplifier.
Combines a high mu triode and two independent diode units in the 7-pin miniature construction. It permits a single tube to function as detector, AVC rectifier, and audio amplifier.
Miniature duplex-diode, high-mu triode intended primarily for use as a combined detector, amplifier, and automatic-volume-control tube in radio receivers. The triode section incorporates a high amplification factor
The 6AL5 combines two independent diode units in the 7 pin miniature construction. Its high perveance permits high efficiency in either FM or AM detector service.
Miniature diode sharp-cutoff pentode designed for use as a combined detector, audio-frequency amplifier, and automatic-volume-control tube in compact, battery-operated receivers.
The Perfect Choice for Stereo Audio Applications - Ideal as a Balanced Driver. Latest revision providing great musical performance and rich tone. This TAD 12AU7A / ECC82 has especially strong systems which are selected to provide two symmetric triodes. The perfect choice for stereo audio applications and ideal as a balanced driver.
High grade tube. Tweed Up Your Amp! Vintage tone for original vintage Fender tweed amps. The original tube for all those Fender® tweed amps from the 50s. Brings back the original sound to your tweed amp.
Metal duplex-diode high-mu triode. It is intended primarily for use as a combined detector, amplifier, and automatic-volume-control tube in radio receivers.
0A2 or 150C2 - Voltage Regulator, Diode, miniature glow-discharge type.
Twin-diode with individual cathodes brought out to separate base pins. The 6H6 is designed for service as a diode detector, automatic volume control rectifier, or as a low current power rectifier
Combined high-mu voltage amplifier and double-diode detector using the 7-pin miniature construction. It is intended to provide output voltage adequate for full-power output of most beam-power tubes.
The 12AT7 is a miniature, high-mu, twin triode designed for use as a grounded-grid radio-frequency amplifier or as a combined oscillator and mixer at frequencies below approximately 300 megacycles.
Tweed Up Your Amp! Vintage tone for original vintage Fender tweed amps. The original tube for all those Fender® tweed amps from the 50s. Brings back the original sound to your tweed amp.
Low-noise Tube for Best Clean Tone! The TAD Selected 5751 is Tube Amp Doctor's first choice for noticeably improved clarity, smoothness, and a true vintage tone character for most guitar amps!
Duplex-diode high-mu triode designed for use as a combined detector, automatic-volume-control rectifier and audio amplifier in a-c, a-c/d-c, or automobile receivers.
Miniature tube containing three high-perveance diodes and a high-mu triode in the same envelope. One of the diodes has a separate cathode connection. The tube is designed for use as a combined AM and FM detector and audio-frequency amplifier.
Miniature, medium-mu twin triode designed primarily for use as a vertical-deflection amplifier in television receivers. The two sections may be employed in parallel, or as a combined vertical-deflection amplifier and vertical oscillator.
Miniature, duplex-diode, high-mu triode designed for use as a combined detector, amplifier, and automatic-volume-control tube
The 0B2 is a two-electrode, inert-gas-filled cold cathode miniature tube intended for use as a voltage regulator.
