AR 5 caps

I have a pair of Model AR 5 speakers and I'd like to recap them.

I was inside them summer before last but lost my list of caps and their specs, is there a reference I could look at?

I tried going down the list of drawings, the file names are numbers; without a key or cross reference you have to

go down the entire list to find the drawing you need.

Take a look at this. Caps should be 50vdc minimum but can be higher. Use film or npe.  Many here would use film for the 4 and 24, and npe for the 72 but you can use film for all or npe for all. Film lasts forever, npe is cheaper

edit: bad link please see my next post

Looks like my link didn’t work. Try the link in the first post here 

Carl wrote 50VDC minimum for the caps, not AC. Doesn’t matter. Most of the modern caps will be at least 100 vdc

Very few crossover caps, new or old, are labeled as "AC" or "DC". Old caps are usually just labeled as VNP. For example the AR-5 Spragues in speakers I recently repaired are labeled 24UF-50VNP and 72UF-VNP. Most modern crossover caps, even if the label is printed with a DC value, are typically labeled as xxUF-100 VNP or higher...which is sufficient for even the most demanding listeners.

Once again, to avoid the inevitable confusion caused by such minutia, it is really not an issue. None of the major capacitor retailers are selling crossover capacitors with inadequate power ratings.
