In Reply to: A final (I hope) question about main-PS (600VDC) caps for my Frankensteins posted by jeffreybehr on April 20, 2014 at 19:05:05:
First I'll remove the original caps and their mounting bracket and splice a few wires that run thru it so that I can reinstall the original if I wish.
After replacing the original cap bracket's chassis-ceiling-reinforcement function with maybe a couple aluminum angles, all subsequent sets of main caps will be mounted on some sort of platform that can be removed and replaced fairly easily. Fortunately, there's lots of room in the amps.
After considering many 600VDC-and-above main and bypass caps, the first set back in will likely be a combination of 630VDC Obligatto* film-and-oils in 70- and 47uF with a 39/630 Clarity ESA* for 156uF. I'm still considering the 143uF WIMA DC Link 700VDC cylindrical...

...as the base cap, to be combined/'flavored' with probably the Obligatto film/oil. At $44 per 143uF for a 700VDC metallized-'propylene cap, this WIMA is the bargain of any I'm looking at.
Bypasses will be some combination--and probably all of--a 0.47/600 Reliable RT ('styrene'), a 2.2/600 Jupiter HT (beeswax/paper/aluminum foil), and a 1.8/1200 Mundorf SO, all 5-star caps in my world. Probably I'll mount the bypasses NOT on the main-cap platform but directly on the ceiling of the amp.
Pics later.
