Capacitor Question

[Texun]

I'm replacing caps in an old tube amp and have a question or two. It's been forever since I did this kind of work and even then it was more of a hobby, bu I don't remember what this type of cap is called. It has 1 lead on one end and 2 on the other and it's a 25MF-25MF-25V.

It's 2 caps in one but what's the official name for this type of cap? Since it's marked 25mf-25mf-25v can I replace it by laying two 25u x 25V axial electrolytics in parallel?

Many thanks!

if you mean having two electrolytic caps with a common ground to the chassis (in the pic) and the positive legs one each going to those two solder points - then yes it certainly appears so. i can see one leg is labeled (+) is the other labeled (+) too?

they seem to be called 'multi section cardboard capacitors' or 'dual section electrolytic capacitors'

Once you confirm the values on the multicap, you can replace it with 2 singles as long as you wire it the same way as the multicap was. It is also handy that most of the newer caps are smaller than the older caps used to be so the need for multicaps diminished and the singles can normally be crammed in the space fairly easily.

The existing caps have +25-+25 one one end so I'm reasonably certain they are in parallel. I have three to swap out and will order six 25u\25v caps to replace them with. Thanks!
