OK, just wondering. Of the last bag of twenty-five 10 uF 450V electrolytics I bought from Bob at radioantiques.com , one failed prematurely in a Philco 60. (Fortunately, it failed open, not shorted, so it only caused a loud hum, not failure of the rectifier.) The others have been OK so far. First time this has ever happened with any caps I have bought from Bob.

In your 116, with a higher input B+ voltage (especailly if you were to run it at full line voltage), you may have to switch to a 500 volt electrolytic. There is someone who sells these much cheaper than anyone else I have found so far on the Web - Studio Electronics.

I think I might try some of these in some future projects of my own. I have some high tube count sets yet to restore, such as a 116B, two 16Bs, and a 17B - and I think I will invest in some of these for use as input filters in those radios.

I have a small cabinet close by my workbench, and I usually rotate a different cathedral or tombstone in that spot every so often. Right now, my late version 116B is on the cabinet. Next to the cabinet, I have a metal electrical box with a power cord, a dual receptacle, and a bucking transformer inside which drops the 122 volt line here to about 108 volts. Whichever radio I have sitting on the cabinet gets plugged into the bucking transformer box, so it does not get full line voltage while it is in operation. (With many thanks to Ed Locker for the bucking transformer box.)
