rich, im responding to your comment about the tube rectifiers

 

when i played one, i think it was 2 mondays ago, it was cool because it was basically a blackheart amp that could actually keep up with a drummer (lol)

 

it does get to kida saturated and muddy, but it seemed to respond well to the volume and tone controls, with the greenbacks it really seemed to sparkle-glassy is a better word i think,

 

 

ill keep you guys informed as i search

Cool, Jesse. Tube rectifiers definitely give a more dynamic response and I love 'em for everything but high gain. The amp I use with my band (Mesa Stiletto Deuce) has a switchable rectifier section to go from solid state to tubes and, everyone once in a while, I try to go with the tubes. It feels really good but the amp just doesn't cut through the way I would like it to. Maybe I need to cut down on some of the low end but I do love the bit of thump I get and it just turns to trash when I switch to the tubes the way I have it set.

a question

are jtm45s class A?

 

Nope - A/B - push/pull. Jim Marshall copied the Fender Bassman circuit' date=' substituting a few values and using different power tubes. And the rest as they say is history!

 

Here's a great link tracing Marshall's history with schematics of all the amps!

"Muddy" only when driving the amp pretty hard. Tube rectifiers can't react as fast as solid state ones so that translates into more compression or "sag" which is a great thing when playing clean or with some mild overdrive. But, when you play with more overdrive, like hard rock or heavy metal tones, that slow reaction time becomes a hindrance as the amp sounds muddy or flabby or just plain mushy in the lower frequencies.
