I use 450-500V Panasonics for the transformer sets.
I usually use at least 200V for AC/DC without doubling rectifiers and 450-500V with those.

This time, I had only these, 47uF 160V Nichicons Hi-rel/Hi-ripple I bought to redo Zenith 5G500 many years ago, having spent 47uF 200V from Panasonic.
And I could not use anything else as I needed to fit 4 of these (80uF+40uF+40uF / 150V) inside plus the 40uF 50V (smaller but still using space) into that twistlock.
I decided they were safe to use as their rating of 160V exceeds the original 150V rating.

But I also noticed that the Nichicon 47uF 200V cap from the same USC series is of exact same size and exact same ripple current rating. Why I haven't bought it...perhaps it was not Mouser stock. Or perhaps I simply haven't noticed it.
But I used up the last four 47uF caps of a suitable rating I had.
Any other combination would simply not fit into the cap.

So. I think I am OK, as with he new resistor I will not even exceed the 160V, plus, again, the surge is allowed up to 1000 times for 30 seconds at 184V, which I am not even close to now.

Comromises, compromises.
