Jeff, It is a blissful dilemma...having distinct differences in output tubes. + NOS Platinum, input tubes...my Mullard's are diff' from my Ediswans, 6n23p ....my two Pair of Tungsrams distinctly different too. I have not decided yet, which of the Tung's' I like best in my Audio Research LS-2B MK II.
.....the bad Ass Telefunken's as my inverter's, continue to amaze in their purity of getting out of the way!
Norm, did you keep the GL KT77's? I'm curious to someday try a quad of those too.
......grabing my 2nd mug of MAJOR DICKASON's BLEND....heading up to fire up ....my ZMA/KS6063/Acoustic Zen Adagio heaven....7:36 am CST....till Noon.... Then down to BAD WEATHER BREWING outside, for a Pint or two of HOPCROMANCER.........
