I have aquired a power supply using 28 x 2N3772 power transistors bolted to two heatsinks which came from a military surplus store on ebay. I took the transistors off as I just wanted the heatsinks for an amp project. If I were to put them back on the heatsinks what could I use them for............any ideas?
Well, with a 60V rating you'd be restricted to a +/- 30V supply maximum. You could make a high current stereo amplifier for driving low impedance loads. Or if you happened to remove 4 transistors (2 from each heatsink) you could make a pair of bridge amplifiers which could do nearly quadruple the power per channel
The transistors can carry 20A a piece, it just depends on how large the heatsinks are on how much you could dissipate.
They aren't particularly fast transistors, maybe a large subwoofer amp in bridge mode & a single channel but with 6 transistors per side (+/-) & two amps making a bridge.
Leaves you with 4 spares

Military generator regulators are common - huge sink with many 3772s could be the back end of a 65Amp regulator. Such regulators are used to smooth out supply to be distributed to complex electronics on instantly deployable systems in the field ...such as mobile radar - rapier guidance - laser targeting - comms etc.
why complicate your life? just use the heat sink for your project.you bought it for that reason right?

Woah, I'm not the thread starter.
Thanks for the replies guys.
Looks like the consensus is that they are not really suitable for an audiophile application so I think I will just settle on the Laser ranging and Rapier guidance system that PhaseLockLoopy suggests
Actually, that might be a bit time consuming so I will just use the heatsinks for my intended original project as suggested.
