Hi, I bought a kt 120 amp with 4 6922 and 2 12ax7 front end tubes. 12ax7’s are the more crucial tube.
I’m familiar with the 6922 tube and have a stash of amprex, Valvo and so on. Not so much on 12ax7’s. I bought some used Mullard 60’s Blackburn, Telefunken’s and RCA long black plate.
I like the Mullard and rca but not sure yet on Telefunken need more time with it.I’m wondering if anybody is familiar with the Tungsram friend had same amp as me and said it was his favorite in the amp. Tungsram is Hungarian and so is the amp, maybe it’s voiced with the amp.. Also curious about the Mazda tube or any other tube. Any help or insight would be appreciated.
