Okay, I probably can't give as much info as needed, and I can probably eventually track this down on my own, but right now I'm a little stumped. I bought this as somebody else's project that they completed (built chassis) and knew it had a distortion problem when I purchased it. Right off the bat I found some wiring issues but nothing that would have caused the distortion problem (mostly ground and lead dress). I also have the parts on hand to make a complete new board and drop it in, but part of me wants to track down the problem. So, the amp was built with 5E3 transformers and appears to be pretty well made (except for no center tap of any type for the filaments) and I believe it's actually louder than my own personal 5E3 build when run through the same cabinet. That seems odd alone given that I used to own a 1960 Harvard and know what to expect. The amp more or less seems to function as it should, except there is an excessive amount of distortion and almost no clean even with the volume down and trying to tame it with pick attack. There is the underlying clean tone that is equally as loud as the distortion on top of it (and it seems to be musical distortion as opposed to noise). The details that I have been able to nail down are that the voltages are all about 20% high, most likely due to the power transformer from a tweed Deluxe, and I haven't been able to find any bad solder joints anywhere as of yet. Plate voltage is 380-392 depending on bias, the plate voltage on the 6AT6 is about 200V, and I can bias it anywhere from a low point where crossover distortion is definitely noticeable all the way up to 100% dissipation. I haven't been able to take any other tube voltages because I have serious back problems and right now with the back pain my hands are a bit too shaky to feel comfortable going for the pins that are more hidden. All in all, it really sounds like it simply has way too hot of an input signal that just can't be tamed, but I get the same results with all guitars and all have relatively weak pickups. Any ideas on where to look before I tear it apart and rebuild? I do have an oscilloscope but don't really know how to use it. I've located problems in amps with no sound multiple times before using a signal tracer, never had to figure out how to tame this type of distortion. Thanks..
