The schematic for the Stasis 2 & 3 shows polarized capacitors. Their appearance matches tantalum caps, (shiny gumdrops).
Research shows they should be replaced during repair or rebuild but there's no agreement beyond that.
* Mylar?
* Electrolytics?
* Polypropylene film?
Must the replacements also be polarized?
I see these: 0.15uF/50v (qty 2 per channel); 4.7uF/25v (qty 1 per channel).

I would definitely go for polypropylene caps. By the way I would replace that 6.3v 470uf electrolytic in the front end with a Elna Silk 2 cap. You have noticed that Nelson has a redesigned front end for that amp haven't you ?
Are you talking about the optical bias version? I don't have it. Is there a bare board or schematic for purchase?
Depending on what fits physically, I try to use polypropylenes for values below about 1.5uF, and Nichicon MUSE bipolars for greater values. Tantalums are the LEAST reliable of all electrolytics IME.
