Tube Amp Doctor - ECC83-CZ Premium - Preamplifier Tube

Save $10.00
Original price $79.00
Current price $69.00

Delivers big and warm sounds, mellow top-end and emphasises punchy mids

Selected ECC83 for the big & warm clean sounds (great for HiFi too!) and mellow top-end when pushed to overdrive. Our recommendation if you want to emphasize punchy mids. Especially great when pushed into a fat overdrive.

 

Q: When does a preamp tube become a Premium Selected tube?

A: All preamp tubes labeled Premium Selected have passed the following tests:

  • Low Noise Test
  • Microphonic Test
  • Gain Test
  • Sonic Tests
  • Shock Tests
  • Listening Tests
  • Balanced Output Test

Matching and Selecting Options for Preamp Tubes

Matching in Pairs for preamp tubes means that two tubes show identical gain, hence, four characteristically identical systems. This matching method includes our Balance-Selection. We highly recommend this matching method for hi-fi systems.

TAD Premium Selected/Highgrade tubes are guaranteed for a period of 6 months (according to terms of warranties) for the quality criteria mentioned above.
