Default NIGC input resistor

Assuming that I add a series step attenuator to the NIGC gainclone based on Peter Daniel's schematic, can I opt out the 220R resistor at the input and the 22k to GND.

What attenuator/volume pot value reccomended?

Has anybody try Elna Cerafine for the 1000uf PSU cap. I never came across somebody mentioning about it in this thread. Is it that bad for Gainclone?

As long as the voltage is OK (ie 50v), the Elna should work fine. I think most people have a hard time finding the Cerifines and is why they are not discussed. I have a small quantity of the Elna Silmics and have no problems.
