Simplistic NJFET RIAA

Thank you👍 What about C3? From the UFSP BOM it seems to be a bipolar electrolytic. There is no reverse voltage to be expected in this position. Would a regular cap, like Panasonic FC or similar work well? Any ESR specifics for this position? And are C2a / C2b to be installed both or is a pick one according to taste situation?
 
For C3, This was originally a Nichicon Muse KZ in kit and boms. These are end of life. For using a FC cap, it's more or less a UBIB, so can use 33uf-100FC here as well. I still have a stash of KZ caps in 33uf.
C2A has a limited footprint, so FC, FR fit well here, and Nichicon FG if you can find them.

See original UBIB Notes regarding C2-C3.
