TAD ECC83-WB Premium Selected - Matched Pair | TAD Premium Tubes

 

The new TAD ECC83-WB PREMIUM Selected

is a low-noise and low microphonic version of the 12AX7 that even meets the specifications of a 7025.

 

The TAD ECC83WB Selected was tested and selected for low noise and low microphony perfomrance.

The Tube Amp Doctor ECC83-WB Selected has a balanced tone with a slight emphasis on the upper mids, which gives the sound a nice string attack and clarity, while maintaining a strong and defined bass range. With the extra kick in the upper mid-range, the TAD ECC83-WB  PREMIUM Selected also does really well in vintage guitar amplifiers.

If the TAD ECC83-WB  PREMIUM Selected is used in hi-fi audio amplifiers, the tube adds a bit of freshness and presence to the signal.

 

The TAD ECC83-WB Selected can be used instead of ECC83, E83CC, ECC803S, 12AX7, 12AX7A, 12AX7M, 12AX7WA / WB / WC / LPS / EH, 5751, 7025, CV492 and CV4004.

 

Compared to the RT003 and RT001, the RT093 shows a little more edge in the high-mid range. As a result, it asserts itself tonally very well, which makes perfect sense in a band structure.

RT003 has a more central tone and thus brings more warmth and a little less brilliance and depth definition than the RT001 and RT093.

Due to their tonal structure the RT093 and RT003 are somewhat less sensitive than the RT001 when used in extremely microphonic sensible applications.

 

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

 

 

We call the tubes SELECTED which have passed above tests and thus qualify as reliable all-round tubes of their type.Typically this is around 30-60% from a batch that receives the SELECTED label from TAD.

For applications in particularly sensitive functions such as V1 or input stage with combo amps, V1 in high-gain amps, tube microphones and phono preamps, we recommend using the respective HIGHGRADE selection

 

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.
