I am replacing the caps on a solid state sound board from a 1969 EM Williams gun game.
The board works OK but I would like to see if the sounds I hear are the original sounds or aged sounds due to old components.

The 1000 and 100 mf caps are alum. electrolytic axial and I have found Nichicon pieces at Mouser (smaller sizes).

I'm not sure what the smaller caps are called so I can search correctly. The old ones have a silver band on them (polarized?).

What I can read on them is:

.047 mf V161-395 Aerovox
.05 mf 200Vdc V161-127 Aerovox
.15 mf 200Vdc V161-398 Aerovox

What info would I search for on Mouser?

Thanks.

Are these capacitors polarized? Or what does the silver band mean on the old ones?

Thank you very much for your information and help!

Thank you all for the concise explanations. I am now a bit more knowledgeable!

To finish off topic for posterity; I picked up the caps at Mouser and replaced them on the board.

Although the actual sounds are the same they are now louder and seem more distinct.

So the total process of board removal, cleaning contacts, and replacing caps was definitely worth it as a whole.

Thank you again for the help.
