Best caps for restorations

Post by Raymanretro on Thu Mar 11, 2010 8:10 pm

I`m familar with the Sprague brand being a good cap but I`m wondering which caps work best for these old sets? Do you use new or NOS? And where is the best source for new. I see a lot of nos on ebay.

I personally wouldn't use NOS
Especially caps, as if they are still in packages they have deteriorated.

I think they are referred to as "Bumblebees". Regardless, they are not really electrolytic, but 47 mfd seems a bit high. Are you sure it's not "mmf"?

Sounds more like .o47 mfd. Should be 600 volts.

No prob. Some of those schematics are very hard to read.
Hope you get it working soon. Please come back, and, let us know. Post often.

I use Xicon capacitors, available from Mouser and others, at attractive prices. I've never had any trouble with them.

I would not recommend Xicon. Another restorer and long-time electronics guy posted he ran into a batch of Xicon's that had bad ESR (equivalent series resistance). My experince/feelings are I do not trust a manufacturer that does not put any date code on their parts. Every Xicon cap I've run across has no date coding and the same basic colors. You literally can't tell if they are 15 days old, or 15 years old.

I personally buy Matsushita (Panasonic) and Nichicon capacitors. They have been industry leaders for decades. I get them though Mouser.

I use whatever i can buy from Fair Radio Sales, Parts Express or Mark Oppat.. Usually Fair Radio due to only living about a mile or 2 away from there.. They are priced about the same as elsewhere usually.. I have preference on brand or style as long as theyre new and work for what i need them for.

I still like Xicon electrolytic capacitors and highly recommend them. As I said, I've never had any trouble with them.

Those are called "Black Beauties" and were made by Sprauge. If you cut one apart you'll see it's nothing more than a wax-paper in a plastic housing and they have problems just like regular wax-paper caps. It is not a 47 uF cap - that value is too large for this type. What color are the stripes on it?

I personally don't like the orange drops. They are of superior quality, but the lead configuration doesn't lend itself to easy insertion deep in a rat's nest of components. I've always had good luck with the caps from justradios.
