The marshall plexi is basically a copy of a fender bassman using british parts... more iron in the transformer, more gain and wattage and of course el 34s... I think the plexi circuit was different from the Bassman circuit. I believe you are referring to the Marshall JTM45, which was a Bassman with British parts...and I want to say even a 6L6 power section for a little while.
