I don’t know if you tried them, but NOS Mullard 6201 are a great 12at7 variety and they sound incredible in my preamp
Replace a 12at7 with a 12av7?
I have a Jolida Fusion 3502P and I've become an obsessive tube roller in the last six months.
The stock configuration is 12ax7s in V1 and V5 preamp sockets, and 12at7s in the V2 and V6 power driver sockets.
It's a fairly robust amp, but am I risking my pricey 12ax7s if I replace the 12at7s with 12av7s? I've found a few NOS 5965s in my stash, and honestly, I prefer the sound!
