I'm planing on an ST35 build in the traditional chassis. I've read that some people mod their ST35's by adding switches to the output tubes for Linear or Triode mode. After I get this amp up and going, I was considering adding the EFB Performance Mod. That one is a tight fit in the original chassis.
I'm wondering if both are necessary. How many people feel the Linear-Triode mode switch is useful? From what I've read, the EFB Performance Mod is a winner, so I'm wondering if doing just that mod would make this amp more than suitable for any application.
