New Compact Monoblocks

Posted on ABSE binaries, my compact monoblocks recently completed. 50 WPC; 
they clip at about 57 W.
Built on a Hammond steel 10x6x2 chassis. No schematic drawn well enough to

post, but if you know an Eico HF60, these are not much different. 6SJ7GT 
voltage amp, 6SN7GTB LTP, Sylvania / Phillips 6550's. Interestingly, these

started life as an all triode project but morphed into ultralinear w/ 
pentode voltage amplifier. The operating points for the 6SJ7 mostly came
out 
of a '46 Sylvania tube manual resistance coupled chart. These charts have 
measured
harmonic distortion specs included, something you don't get with the
typical 
RCA RC charts. Check out them Tweak Interconnects, original Dynaco's.
Thanks for looking.
