RE: Low noise resistors?
Posted by 13th Duke of Wymbourne on August 16, 2021 at 17:46:31:
Are the 100 Ohm in series between the cartridge and the input devices? IIRC, about the best input referred noise for an audio transistor amplifier is approx 1nV/rt.Hz (e.g. MAT-02 and, I think, there is a J-FET can reach that too). Adding a series 100 Ohms is about the same as adding another 1nV/rt.Hz so the system noise doubles.
