Just wondering if anyone has experimented with using 12at7's in a dual rectifier..
Either replacing V1,2&3 or replacing just one..
Given they are a lower output,
I'm wondering if they would tame the fizz and gain or just push it back further requiring you to turn up the dials?
Any thought or experiences?

Yes, I have used an NOS (RFT as well as JAN-GE) in my Roadster. I only ventured into the V1 or V2 positions. Never try a 12AT7 in a cathode follower circuit as it will not work well. I was impressed with a NOS JAN version of the 5751 in V2. Actually sounded much better than using current 12ax7's.
