So I have been collecting parts for a while, just random bits here and there over the last 20 years, and normally don't need to do much high-current power work. (I usually work with vacuum tubes at RF!)
I've been working on a silicon transceiver for a few years, and it will need a 13.6v, high-current, low-ripple/low noise power supply. The final amp has pretty bad PSRR, so the smoother, the better.
I've got a 16V center-tapped, 30A power transformer, a few 50,000uF/50V filter capacitors, and some 40A power diodes. All good there.
Going through the power transistor bin, I have:
3 each Fuji Electric 2DI 100Z-100-01 darlington bricks-Untested, not sure how to test this?
5 each RCA 2N6051 PNP TO-3 power transistors-these are new in the package
2 each ECG280 NPN TO-3 power transistors-these are new in package, audio finals
1 RCA 2N3055 NPN TO-3 power transistor-New
I have LARGE heatsinks available, rated for 1KW plus in industrial service, and the one that those three Fuji bricks came on was rated at 14KW. I am leaning towards the 2N6051's because they're available if I blow one up, but they are PNP so would have to put them in the ground rail-which is good, the heatsink would be grounded.
I haven't done a silicon power supply over 3A in a decade-and even then that was just a pass transistor around a LM7805. I've always had good bench supplies for everything I needed until I hit this high-current need.
Does anyone have any schematics to share, with insight on how I might want to change them for this application? Tim? I can't find your old schematic repository anymore, I think it moved a few years back.
