I'm about to bite the bullet and pick one of these up because my wall voltage at home is 126 and it makes my amps run way to hot! Don't like the sound at all and these babies were designed to run at optimum around 110 to 112. I need to bring the plate voltage back into range since most of mine are in the 550 range right now. Just wanted to ask supafixer and anyone else where they set the voltage for their rigs to get the optimum tone and longer lifespan. Thanx for any commentary on the subject!
