I have an aluminum heat sink with 8 TO3 transistors mounted on it. Four are PNP, four are NPN. I want to use it to make a 12 volt supply. I could use the PNPs to make the negative supply and the NPNs to make the possitive supply, or I could buy 2N3055s and have a single-ended supply.
But what I'm wondering is this: What is the best strategy -- series or switching? I want to use it for experiments in general, but mostly for radio transmission. Switchers are said to produce many harmonics and I want as clean a supply as possible.
But mostly I want to know this: How do I arrange all these xistors in such a manner that they all work together, combining their amperage. My thought is to combine via parallel connections -- base to base, emitter to emitter, collector to collector -- all the xistors into the role of one series pass xistor and use feedback to control the output.
Any thoughts? I'd sure appreciate it.
