It's not really a Marshall clone anymore, its got elements of a 18W marshall power supply, and thats about it... I have messed with all the components and preamp and stuff, now its just a 50W custom amp, but when cranked will put out "that Marshall tone." With the old Power transformer, which was a horrible tranny BTW, it had about 550VDC on the plates of the 34's and that was the volume I wanted, and It didnt get dirty until it was pretty darn loud, and with my calculations... it said almost 75W but it wasnt that much, I think it was actually around 50 or so. but that was great, except that PT was just a horrible PT... IT made so much noise you wouldn't believe it, and the voltages were too high for anything but the power tubes. and those were marginally high. Anyway, Yea, Will try to get higher voltages, for more power, since that's what life is about right MORE POWER!!!! Just kidding. ;-) Yea I'll see about the PT. I'll get back to you guys.
