For W8JX I can if I run the current on up to 400 or more MA but so far it doesn't' seem needful to do it as except for the duds, the rest have all worked fine.

It has been in storage, not operating. The caps will be fine, no need to replace them. The tubes need only about a 4 hr burn in. It should work perfectly after that.
It's not rocket science.

Aluminum Electrolytics dry out, granted probably would have been faster when warm and operating all these years than in cold storage.  Eventually replace them.

Wonder what it would take to tool up to make a few standard sized oil filled caps with modern materials and dielectric oil to fit in, say, 90% of the legacy, or new, for that matter amplifiers.  Say a nice 4 x 4 x 4, 2500v / 47 uf:   or 3500v / 33 uf, etc. 
Design with a couple of raised posts with adaptor jumpers to match just about any existing printed circuit board.

 Sell them with one high value, high wattage bleeder to replace the myrad of 500k sets of equalizing resistors out there in existing cap stacks.

Probably fairly expensive even in a high end amp,  so probably cheaper to just change out the caps, even the computer grade "Alphas" style high enders.
