Are these capacitors interchangeable?

[diynoob]

Hi.

I'm a noob, so this may be a dumb question. I am assembling a vintage Heathkit amplifier from 1965 (still new in box). I have already ordered replacements for all the electrolytic caps in the kit as based on my research these are probably well past their useful life.

When I ordered replacements for the power supply filter caps, the ones I received are considerably smaller than the originial (see photo). However, they appear to be rated identically. There's no thermal rating printed on the original and I can't find printed spec. So, can I use these physically smaller caps?

Thanks for your assistance!

Hello,

I would say yes. Over time they where able to put more capacity in the same space:

Great information. Thank you very much.

That’s a definite yes from me too.
Don’t forget that you can always increase the voltage and temp rating without adverse affects.
