gary	Re: Marshall 1987 I don't know what the story is but I just wanted to confirm that most all of the metal panel(not the plexi- didn't see many of those) 50 watt heads I worked on in the 70's had about 390 volts on the plates of the power tubes. Most of those were using 6550's and although I don't remember what power they produced clean, they were quite loud. As I remeber the 100 watt heads were mostly ~450volts. These were all the 4 input(1987(50w) or 1959(100w) circuit. Gary
