Can capacitors

In fact, if they are as old as the one's you're replacing, you're probably making things worse because caps suffer more from being stocked unused than having been used.
 
None of the can caps in that link are the correct value for any monitors I'm aware of.

I know some people like to be all original and want to find an exact replacement, but the fact of the matter is that multisection can caps like that haven't been made in any quantity in *years*. Any you're likely to find will be 30 years old already. There's no point paying a premium for a pre-aged part... I'd much rather use brand new, good quality individual caps.

If you really, really, really want it to look all original, you can cut open the old can and restuff it with new caps.

...but remember that the stuff inside them is toxic !

Shouldn't be. The cheap caps used in monitors, tv's and radios do not contain "PCB's". That was only the good, high quality oil caps. Electrolytics like this contain mostly paper, thin aluminum, wax, and a weak boric acid/glycol solution that the paper is supposed to be saturated with. I mean, don't eat it, but it's not going to hurt you if you get it on your hands or anything.

Yep, and refill em with wax if you want to go all out. I noticed my Football monitor has a multivalue can on it, something to do with the x-ray protection circuit I think.

I agree with just replacing the old with something new.

However that was a good point made about those trying to keep the original look as well.

I also came across this info:

You can also buy custom made multi section electrolytics from DH Distributors (888-684-0050).

...but I suspect that they probably just fill the can with a modern equivelant as well... ;)

At school we built a "lab" power supply including voltage adjust, current limiting, meters etc. as a "final" project. We built everything up from scratch including making the case from bare aluminium. (Folding, making the holes, the works).

Most of us spray painted them black. Some of us also did the inside.

There was a really big fat cap in there (not unlike a Big Blue). Despite all the checks, one of the guys managed to have hooked it up reversed. It exploded with some pretty force (while the case was closed). After we opened it up there was a PERFECT circle around the cap where all the paint had completely "eaten" by the stuff from the cap and we could see the bare aluminum again....

Indeed, don't eat and don't touch...
