Probably due to the all copper case !

Nobody uses those dinosaurs anymore. We have proper FET technology. Unless you collect spareparts for antique electronics, bin them..

Dinosaurs or not, I wouldn't knock the value of the copper scrap in them !

Ah, but some of us do use these 'dinosaurs' to repair vintage equipment.

So what's the question? You've made statements, haven't said what you want to know.

Two transistors are pretty minor, especially if you've tossed even rudimentary test equipment. So either keep the transistors because there are only two of them, or toss them because you clearly won't be using them, not when you no longer have test equipment.

Somewhere I vaguely remember seeing a design for a sort of hot plate based on a 3055 for keeping a mug of coffee hot.

The 2N3055 5VDC pass-regulator (heatsink assembly), as used in the 1980 video game Galaga, would keep your tea or coffee warm if not hot...

The one I'm thinking of was published specifically as a mug heater.

Probably something along the lines of a temperature controlled current source into a short circuit.

Probably the best thing to do with a 3055 these days.
