- what is it ?
New Guy
While scrapping an old amp today I came across what appears to be some kind of capacitors mounted to to heat sinks. The capacitors look like top hats and are about 2 inches in diameter and the outer part is aluminum. Does anyone have any ideas what this may be ?

Does it look anything like the top one in this pic?? If so it is a TO-3 transistor. Commonly used in/on power supplies possibly audio applications.

Bipolar Transistor?
I hate being bipolar. It's AWESOME!

I believe I have posted this somewhere before, it's a fairly good example of how to identify electronic parts and what they might contain.

At the heart of science is an essential balance between two seemingly contradictory attitudes--an openness to new ideas, no matter how bizarre or counterintuitive they may be, and the most ruthless skeptical scrutiny of all ideas, old and new. This is how deep truths are winnowed from deep nonsense. -- Carl Sagan

If it is a TO-3, some of them have gold plated leads and some have a gold plated base. Worth looking at when you take it off...

Why do they have a Gold plated base? I don't think that it would help much with heatsinking the transistor.Originally Posted by ScrappinRed
I have noticed this on SAW (standing acoustic wave) devices too, and theres no reason at all to heatsink them.
Theres normally at least one in every CRT, but more modern ones are black resin encased.
Very pretty things to look at if you can get inside the casing.
And..... That LCD screen in pjost's post. They normally have full Gold plating on the board.
I find them in lots of different appliances, microwaves, telephones, alarm clocks, photocopiers etc.

Thanks y'all. That is it, a bipolar capacitor. It had 18 of these in it. I didn't see any gold plating on them anywhere.
