Hi, I found my dream amp, the Tone King Imperial!! I have try one in NY few month ago and I remember is really loud...so I'm afraid I can't use weel in italian small club...It's a cathode bias amp, so I'd like to know: is it possible change the 5ar4 tube rectifer with a 5y3 as the Tweed Deluxe? If yes, this lower the wattage? And the volume too?? Does this get me an early breakup? Thanks so much!!!
