Hi everyone,
I thought I'd share a circuit that I am currently developing to sell as a PCB. It's a high quality RIAA phonostage with an 'electronically cooled' input stage, and also features a rather interesting and unique topology to filter out the antiphase rumble that resides in the stereo difference.
Gain 40dB @ 1kHz
Vertical rumble cut-off 146Hz
Lateral rumble cut-off 14Hz
Supersonic filter 42.5kHz
