12AU7WA / E82CC (6189W / CV4003) NOS/USA TAD Premium Selected

This 6189W is the High-end version of ECC82 and 12AU7A tubes. Beloved for the best tone.
Current stock mainly is SYLVANIA. The 6189W is a direct upgrade for 12AU7A, E82CC and ECC82 tubes.

As NOS stocks change quickly the picture might show a tube of different brand unless the brand is defined in the description. TAD will always supply a tube of equivalent quality type make/brand/origin.

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.
