BOM has 47uF for C32, schematic says 22uf.

BOM also doesn't state what caps are polarity and which aren't. Schematic states they all have polarity, but is that true?

Sorry for the late reply... I wasn't getting notifications of opened issues.
The BOM always supersedes schematic placeholders.
As far as capacitor polarity, all electrolytic capacitors on the board are polarized. Ceramic decoupling capacitors are not.

Sorry, but I mean the schematic file in kicad, not the silkscreen.
The board I have shows R1 = 33 ohm on the silkscreen, but when you open up the sch in kicad, it's 47 ohm.

R1 is not listed in the BOM at all. What do I use for R1 in this situation?

R1 is interesting because the original bare Rejuvenator board is marked 33Ω. But original populated boards have been found with 33Ω, 47Ω, or 68Ω resistors. Consensus was it probably doesn't matter much. It's there to protect Agnus from the flying lead connection, which isn't optimal. Work is being done on the next revision of the board to eliminate the flying leads.
