VAC Capacitors

[Danlampton]

I am working on an older electronic organ and I ran into two electrolytic capacitors that are 50uF/20V AC and 35uF/20 V AC. The only AC caps I can find are for motors. Are these just non-polarized? What can I use to replaced them.

Thanks.

Yes, I assume them to be non-polarised electrolytics; you should be able to find a supplier.
If not, a non polarised electrolytic can be replicated by 2 x regular electrolytics of twice the capacitence value, same / higher voltage rating, connected so that the positive ends are joined, negative ends form the non polarised terminals.
