Re: Supro Thunderbolt Mods
A guy I know has 4 of these, and he modified two of them to have a bigger OT. It breaks up a little less and has more headroom, but still sounds good. The other tow have the stock OT.  
He cascaded the unused triode into one of the other ones in all 4 however, so they have a bit more gain and sound REALLY nice. I haven't got a chance to do a layout/schematic on his amps, but will do so soon hopefully.
