Fyi the best sounding 12at7 that I have heard is a 70’s Tungsram with square metal getter supports. Unusual design for sure and hard to find. These are amazing better than mullards, amperex, telefunkens etc....there is a pair on eBay with the orion brand on them. I would pick these up if you are a chronic roller like me. I would but I don’t need to hoard.. cheers!
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!
