can i sub a 12ay7 for 12ax7?

Tubes Asylum

Questions about tubes and gear that glows. FAQ

My recently completed Croft S2 Clone amp (PPP el84) with 12AX7 input and 12AX7 splitter tubes has way too much gain. I barely have to crack the volume control on my preamp to get a big difference in output. I am trying to reduce the sensitivity of the input section and wonder if I can use the 12ay7 (amplification factor 44) in place of the ax7? I already tried 5751 which helped but still way too sensitive. TYVM, Dak
