360v on a 12ax7?
I wouldn't expect long tube life at that voltage.
Do most Marshall's run it that high?
Design parameters for a 12ax7 usually list 300v max.
But I know that Leo Fender used to exceed those all the time.
But back in the day, tubes were a bit more robust.

Vegard, what can I say about this build that hasn't already been said?!?
Question - on the power board, are those the F&T 30uf or 47uf caps?

Hi!
