Hi guys,

I’m trying to recap this beautiful radio, but I got some questions regarding the values, I’m working in the volume area, and there’s some odd values.

C21,C22 5mfd 6v ......... 4.7 50v will work?

C23,C24. 0.047 50dc........??

In the service manual C21 and 22 both are 5mfd 12v, instead it was installed 5mfd 6v, why?

Chasis 9CT40Z2

Thanks,
Gustavo

Yes, the 4.7uF 50v will work just fine to replace C21, C22, C23 and C24. The 6v caps that you have there are not original, Zenith did not use radial caps in these radios, they used axial caps. Those caps were replace once before and they must have had only 6v caps available. T

Thanks Andy,

C23 and C24 are 0,047mdf at 50v, so you say 4,7uf will work?

I believe the 0.047 capacitor you need is like this one that is for sale on eBay:

No. Replace the 5.0 mfd with 4.7/16 or 25 volts, and the .047s with new .047s, if necessary. In some 1000s, there is a waxed paper cap for one of the .047s, and others, it is a film cap (which is probably OK).

Almost any voltage rating will work for any of the caps circled above, Vcc is 12v, so anything above 12 volts will be fine without having to think about it too much. It's very hard to find lower voltages, anyway. I use 16/25/50V because that's what comes in the "electrolytic capacitor grab bag" kits. They are all much smaller for their voltage than would have been available in 1958,
