Ground loop breaker and RIAA

[BigE]

Hi folks!

I have a quick question. Will using a ground loop breaker in an RIAA section change the filter response?

Thanks!

Can you explain what you intend to do exactly? A ground breaker should not be used in the audio interconnects between the cartridge and pre-amplifier, other than that I am not sure what you are contemplating.

Sorry, my mistake.

*All* grounds (node 0) need to be moved to the ground loop breaker (GLB), which connects PS common and safety earth (which becomes node 0).

I forgot to move PS common to the GLB, but moved all other signal references. This caused the RIAA to change.
