Brand Tubes - glowing advocates of good sound

Brand tubes are dear to us. Anyone who has once played their instrument through a good, matched tube amp with a suitable cabinet and heard it, will find it more than difficult to move away from analog amplification.

Dense, organic sounds, clear development, and a more lively, freer sound design are the results of good and high-quality valves.

Whether our customers need specifically matched valves for preamp, power amp, or other installation positions: Our huge assortment of brand valves perfectly complements our own TAD Premium Tubes and offers the right sound sources for all needs!

Matching - combining suitable valves

Analog technology in general, and tube amps in particular, act almost like organic individuals. Their components interact with each other like organs in a living body. No wonder then, that replacing individual components can impair the overall performance - sometimes with serious consequences for the sound.

Therefore, for our brand tubes, we rely on our proven matchings, where we combine specifically matched valves and offer them to our customers in sets of 2, 4, up to 24.

Our matching is the result of decades of experience in tube technology and is offered in two categories:

Standard matching

Even though the manufacturing standards of our brand tubes are so high, it is beneficial for the components from Haltron, Electro-Harmonix, GEC Valves, or BRIMAR to be specifically matched to each other.

Premium matching

Amplifier valves work together and should therefore be matched to each other. In particular, the individual gain performance of each pentode or triode must be matched.

Selected quality - our testing conditions for brand tubes

Our experience has taught us: Life is too short for bad sound. Therefore, we rigorously test our TAD brand valves. And only the best receive our Premium Selected designation.

These components meet the highest standards and have passed the following tests with flying colors:

  • Noise Test
  • Microphony Test
  • Gain Test
  • Acoustic Tests
  • Shock Test
  • Listening Test
  • Uniform Signal Strength / Performance Test

 

Such tested components, whether pentode, triode, or preamp valves, meet the highest requirements to do what we all want in amplifiers: Sound!

Ordering brand tubes from Tube Amp Doctor - precision and passion

In 1993, we decided to enter the market with amplifier valves and components for amps, speakers, and the like. Our enthusiasm for handmade and authentic tube sound has only grown since then. Today, we can offer our customers selected and hand-picked goods at fair prices, giving them the necessary tools in their search for their own, individual sound. With over 650,000 components in stock, service in wholesale and retail, and a love and enthusiasm for good sound, Tube Amp Doctor is here to support all musicians with advice and action! Convincing service, convincing brand tubes - that's Tube Amp Doctor.
