This is the very best 12AU7 type I have tried and I have tried a TON. I am willing to put this one up to "any" 12AU7/5814 type on the market, period. Tested in both extremely high-end and very lowend/budget stuff, and the tubes just work magic. Don't ask me, ask the tube! These are the two mica, gold pinned ones. The three mica is a good tube, but this is the very best.
$80 or best offer for a pair.
Thanks!
