TAD ECC83-WB "Premium Selection". 9 pines
Low noise and low microphonic version of the 12AX7. 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. If the TAD ECC83-WB PREMIUM Selected is used in hi-fi audio amplifiers, the valve adds a bit of freshness and presence to the signal. 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.
