It doesn't matter. If the value is small and you can omit using electrolytics, do so - electrolytic caps are a limited life part.
But if you do use them, observe the polarity.

Thanks Skyscraper. The caps in question are 10MF and 40MF. Due to their higher value, would it be okay to use an electrolytic? Which would be better?

Here is the schematic and diagram: http://s270.photobucket.com/user/Colorad...ent&page=1

Those have to be electrolytics I think. I also think it is a doubling rectifier so the voltage ratings you use have to be about 350V. That is 250V DC will not be exceeded if the load is disconnected (hence the 350V rating to have margin) and normally it is lower (175/110V for 40uF and 10uF respectively) but this is if the load is OK.

So, use electrolytics 40uF and 10uF 350V.

Thanks to everyone for their assistance. The 60hz hum is now gone and the radio sounds pretty good for having the original (from what I can tell) speaker. Now on to the record player portion of the unit.

The cap with the wire wrapped around it is a crude LC circuit intended to make the chassis have a low impedance connection to the radio B- supply line at the IF or RF frequencies, but have the impedance be somewhat high at 60Hz. Radio could oscillate without it. You could carefully slide the coiled wire off the old cap, keeping the turns spacing the same, and putting the coil over a new cap.
