Just arranged to return a CE can cap (20uFX4 for my Princeton) to AES for full credit toward 4 Sprague Atom axials I plan to strap together inside the chassis to replace. This is the first time I have ever had a problem with Antique Electronics in about 15 years of doing business with them. Hope it's not a preview of coming attractions.
Can caps are not up to the job, obviously. This is the third to fail for me, and I decided to go with the 4 axials after seeing many online complaints. AES either owns or has some interest in CE, the manufacturer of these can caps, so we'll see if they make good. The CE cap was so bad it generated heat sufficient to make the front panel too hot to touch. I'll keep you posted on this.
