ARC SP-8 replacement B+ filters


I'm about to replace the OEM Mepco 200uf450v B+ filter cans in my SP-8. Just wondering what's the best current production replacement? She has developed an abnormal breathing action. Which is noticeable on both the a/c line as well as the output. I've had her out of rotation for a few years. And I noticed this while slowly ramping her up on a variac. Any recommendations on which cap to choose?

Thanks in advance,
If ARC has them, get the caps from them. They now use better non twist lock-lytic caps on a special little circuit board so they fit in the board properly.
