I just picked up a partial amp off of ebay which is the same as you schematic. Do you still have it? Do you like it?
Thanks,
Dave

 Congrats on your find! I also found one in need of repair, on the east coast. It just needed some resistors replaced and caps updated to come to life. It sounds good! I also have the earlier 6V6 version of the same amp to side-by-side compare. The 7591 amp is stiffer and more responsive due to the diodes in the PS. Love them both! Thanks to plexi50 for posting the schematic!
