Will do a powered speaker as you suggest Mark, it's on The List.
Amps finished... kallooo kalay oh frabjous day... : ) Everythings tweaked, mucked about with thrice, altered, redesigned, put back as it was then redesigned and tweaked again. They sound right gradly, THD 0.28% @ 112.5w, F response 3dB at 33khz, N = 20mV, no idea what that is in dB, here's some pics....
Re the meter after mucking about trying to draw a scale I thought sod it, and decided to paint it black. I quite fancied a meter as per the Disater Area spaceship in hitchhikers, EG black on a black background with black lights, but decided to cover the pointers in gold leaf by way of contrast.
