Replacement capacitors for 600 receiver?

[drabina]

I am trying to find few replacement capacitors for Fisher 600 receiver. I did search here on Fisher sub-forum and found couple of posts mentioning Nichicon UHE or Cornell Dublier DME. Unfortunately, none of those are available in axial form thru Mouser or Digikey.

Could you guys recommend good alternatives? The capacitors I am looking to replace are:

100uF 25V axial
200uF 35V axial

Thanks.

Try a slightly higher voltage rating, like 50v, see if that helps

Up the voltage....and then search.....


Or don't be married to the manufacturer:

Or buy top shelf.... or well for that matter:

A beer or two always helped me find stuff :beer:

The DME series is a fractional uf cap (ie .47uf etc). UHE's I've found start with 50V. Gonig from 25 to 50V won't hurt anything, all you are doing at that point is giving the cap some headroom as far as the circuit voltage. Ive seen circuits run right at the caps voltage limit in these, and with the increased line voltage, the circuit voltage is usually higher than the cap is rated for.

One other thing. Values on caps changed in the early 70's. So a 200uf cap would now be a 220uf cap. a 50uf cap will now be a 47uf cap. Adding a zero to the end or going fractional the changes are the same. 2000uf now becomes a 2200uf, a 500uf can be a 470 or 560uf, and a .5uf would be a .47. .20 is now .22. 20% variance is allowed in most all caps from that era. Many were as high as +80% / -20%. It seems confusing now, but you'll get it real quick.

So the caps you are looking for would be a 220uf 50V and a 100uf 50V.
