I have not seen this done. Perhaps it is due to the capacitors shunting to ground, and not affecting the signal path. MLCC caps are what I have used.
Silver Mica Caps on Phono Inputs
Hi there, I am curious if anyone has used silver mica caps for bypassing RF noise on a phono input and what their experiences are? I'd like to use them to squash RF coming in from the phono cartridge to the preamp, so they are shunting the input lines.
I could use polypropylene or polystyrene but the RF characteristics of a wrapped cap is not very good for shunting RF noise to ground.
