The Sovtek 12AX7WC has a little bit more gain than the Sovtek 12AX7WB and  the 12AX7WA. The noise floor is still pretty low compared with other 12AX7 tubes and the dependabiliyt very high.

4 tubes, matched as quad

EL34 II has fuller low mids and low end but does not lose headroom in the high end. Stronger than regular JJ EL34 but not as aggressive as the JJ E34L.
