Quick question. All 8 of my voice cards have a majority yellow 22UF/25v caps on them with a small number of elna black caps of the same value (replacements )Not sure if this was an engineering change to the xa but the 3rd version schematics do shows 15uf.

Anyway, all the the schematics show these caps as 15uf/25v. I have quantity of both 22uf and 15uf caps to do the job. Any opinions on this

Also, can anybody point me towards a 100K high resolution pots for the oscellator that has proven to work good
