Should be fine but be aware the 12av7 is a hotter tube. It uses 150 mA more on the heater grid. A pair of tubes isn’t a lot. Gain is 41 vs 60 on the 12at7 so it may need a little extra power. Your ears are the answer...if it sounds better to you then so be it. Good luck.
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!
