RE: Looking for 60's 6P3S-E's...

Posted by Detune on February 23, 2017 at 21:22:45:
Wouldn't doubt it. The ones that came from Bruce in this MOFO sound pretty great, especially biased SUPER HOT and with Mullard f91/f92 long plates in V1, V2, and V3.

It's a question of trying the old 6P3C-E's or perhaps sacrificing real XF2's in this bad boy, as the JJ KT77's sound INSANELY GOOD yet die so quickly...550 B+ and mere 470 ohm screen resistors make for a vicious electrical environment for all but the strongest of valves.
