Hey guys
Recently I picked up a Krell KRS 2 preamplifier that had supposedly been sitting in storage for the last 20 years. It looks brand new both inside and out but upon further inspection it appears that a few of the electrolytic caps are cracking. I've seen caps bulging before but never cracks, one would assume this unit is due for a re-cap? I have not yet tested any of the caps with a meter.
I did take a quick look around Mouser and Digikey for the cap values but I'm having a really hard time finding anything in 14.5MM diameter. If it does indeed need a re-cap I'd like to keep the form factor the same as factory if possible.
Ignore the broken phono ground in the last 2 photos, Shipping wasn't kind.

It was common for the plastic covering on those to crack. They may be perfectly ok otherwise.
Replace capacitors on the basis of electrical measurements, not the plastic covers cracking.
There are often problems caused when parts are replaced unnecessarily.
Also, a similar form factor may be hard to get in new types.
