When I replace those I have noticed that modern electrolytic capacitors have two leads however these old capacitors have what appears to be one "nipple" on the bottom of the shorter capacitor labeled 16mfd and 4 leads on the larger capacitor labeled 8mfd 8mfd 10mfd. how do i go about connecting these new capacitors? Also, I cant seem to find out what the voltage for these capacitors should be.

This is tricky to explain in words but I'll do my best. The old type can cap with the "nipple" on the bottom is a single section cap. The can is negative, the nipple post is positive. That corresponds directly to your new caps.

The 4-wire, three section cap is #67 at http://www.nostalgiaair.org/PagesByModel...013811.pdf

The negative lead is common to all three of the individual caps (8, 8, 10). The positive leads go to their appropriate destination and the negative lead connects electrically to the center tap of the transformer, not the chassis.

Now here it gets tricky for the first timer. Negative does not mean or imply ground or chassis. Often it does but you'll encounter those can caps mounted on insulated wafers to isolate them from the chassis. There will be a ring lug of some sort on the threaded mount where the negative connection is made. In the case of your 3-section cap you'll see the POSITIVE of one of the sections goes to chassis. That's the 10uf in the diagram.

As for voltage....in most radio work on models such as this just use 450v electrolytic caps and call it a day. That 10uf section could use a much lower voltage but other than a few pennies there's no need for concern.

Makes sense?
