Fergit the 12SN7; Get the RCA JAN-CRC 12SX7; it is identical to a 12SN7 electrically, but had tighter production controls, higher batch sampling, etc. "THE" 12SX7 has mid 1940s datecodes, bottom getters (rectangular)and is reputedly made by GE.(Just like GE made the Red Base RCA 5692)They are the best thing going in an octal medium-mu (6SN7 etc)except for the roundplate TungSols and damn near any 7N7 loctal. Nice treble like the Sylvanias but they have some meat in the mids. Great stuff. The tube center (I think) has them for $30. Just do a "12SX7" search. If you have a variable DC filament supply, don't forget about the 8SN7 too.
