TAD ECC83-WB Premium Preamp Tube
The TAD ECC83-WB s 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.
DISTINCTION from RT001 12AX7A-C and RT003 ECC83-CZ Premium Selected:
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.
