Difficult Time Finding Replacement Caps

Monjul · 1st March 2010, 09:58 PM

I'm looking for replacement caps for a 20 year old Cary amp. The filter caps fit through access holes in the amp and are 1100uf 450v with a diameter slightly less than 2". Cap height is not an issue.

Although I found a replacement (CBE) at Mouser.com that fits the bill, it's a non-stock item requiring a minimal purchase of 16 units.

So my question is, can I use a different value cap without blowing up the rectifier? As usual, thanks for any recs or suggestions.

I'm guessing this will work.

1200uf 450v

with huge Caps like that, I'd choose a high quality 1000uF, rather than worry about the extra 10% capacitance in a 20% tolerance part. The KEMET BHC ALS30 series has a long track record in quality applications:

Thanks, but the BHC has a >2" diameter so it won't fit through the amp's access holes.
