Thanks for the reply smolder. Seems like no one has got any input on tubes especially original sms owners or guys cleaning up a 64-67 board. All I can say is unbelievable difference and unreal sensitivity. Back to back 7025's is just too much for the sms. The worst 7025 readings I was getting approx. 75% on my B&K tester. The other's average close to 85% factory specs.
My conclusion is to leave the best read 7025 in V1 and Brad's 12ax7 in V2 to smooth things out.
Never thought I'd have a problem with to much clean headroom and volume. With the back to back 7025's I had the pad on the back dialed to about 25% and the front about 10 oclock. Even on 3-4 my E's hooked to my 2300 could fill a theatre. Nailing finger rolls like crazy.
I just don't have a building to play with that power, So for you guys who have gigs and don't want to have to crank your equipment buy some 7025 with good readings from GE,RCA or JE. Most guys selling them post the readings in their ad.
I don't know what it is?????You guys just say it's just a heavy duty 12ax7 but playing them especially back to back the way I did there's more to it than that. Gonna put Brad's 12ax7vka or something like that in V2 to tame this beauty.
