Moreplay 2.2uf capacitor voltage rating

[Pandymonium]

I'm currently building a Moreplay, which I'm leaving stock, but I will soon be getting a friend's Moreplay, and I wanted to use that one to try different output caps. The stock cap is 2.2uf 250V. I'm wondering if the pictured cap would be OK to try. I recall reading in another post here that one has to consider the surge startup voltage too, but I can't find the post now. Should I be looking for caps rated higher than 250V? Thank you.

Yes, there is a startup surge in the Moreplay, but not if you have the upgraded power supply installed. The surge is relatively brief and we elected to use a 250V rated coupling cap in the preamp, but I'm not so confident that I'd be up for doing this with vintage Russian PIO caps (some may argue otherwise).

Thank you for the reply. I have some rated for 400V, but they are 0.68uf. How about 3 of those in parallel for 2.0uf?

That is certainly a viable option.
