"any 12A*7 can be rolled here"
In a circuit designed for a 12ax7 a 12at7 or a 12au7 would not perform properly without adjusting the circuit values. There are large differences in mu, plate resistance and transconductance between those three tubes.
I've always wondered why people contend that a circuit can use multiple different tubes without modification?
That belies the facts.
By the way, nice looking amp.
