I've got a pair of Hammond 1620 output transformers sitting around doing nothing. I need to build something with them. While the 6.6K primary impedance would probably do best with a pair of 6V6 or 6AQ5, I've got too many 6p14p around not to use them instead.
I'd like to make a pair of mono blocks. I have several pieces of aluminium plate that I intend to use for the top chassis. They're rather small at roughly 9.2" x 5.8", but I figure if a Dynaco Mk3 can fit in a 9x9 footprint I can make a 10 watt amp fit in two-thirds the square footage.
I'm open to suggestions for the power transformer. Right now my best idea is the Allied 6K56VG simply because it is reasonably cheap at $45 a piece. It's a 540VCT unit with 6.3v and 5v filament windings. I expect to use solid state rectification, mostly in the interest of saving space, and I'll probably have a B+ around 360~380 volts. The 5v winding might go to waste.
I want to keep it all in three tube sockets simply because there isn't going to be a lot of space left on the chassis. I need two sockets for the output tubes since the 1620 is PP. I think I can build a LTP phase splitter and skip the first gain stage, kinda like a Baby Huey. I am intrigued by the partial or plate-to-plate feedback scheme. I'd prefer to keep things primitive and forgo the CCS bias on the output tubes. They'll be cathode biased instead, which I believe is a good choice anyway for the EL84 family. I might be convinced to use a CCS on the LTP, but if I can get away with a simple resistor I will. I'd rather build from an easy printed circuit board and a proven tested design, but this is going to end up being point-to-point and mostly pulled out of my backside.
I have no design software, little experience, and even less talent. If anyone wants to offer up a schematic for me to blindly follow I'd be eternally grateful.
