Hi

Would it be ok to use a 3,3 microF cap instead of the 3 microF described?

These caps are in the RIAA filter, 1% (or better) would be best here.
If you got a lot of 3.3uF with tolerance 10% or 20% you should try to select the ones with closest 3uF capacitance.
Of course you can put here a pair of 1.5uF, or tripple 1uF.
Measure it if you can.

The rest of the RIAA filter should also be the closest possible (493R, 105R and 1uF).

good luck
B.

I received the kit with RIAA resistors 487R.
What is more precise 487R or 493R?

Thanks
