RE: Are the 100 Ohm in series between the cartridge and the input devices? ...
Posted by andyr on August 17, 2021 at 05:10:05:
Thank you 13th DoW - exackly! :-)) They are JFET Gate resistors (for stability).
So my problem is ... what are the best reses to use?
I had thought Vishay VSH were good (in terms of low noise) but, as I can't get them any more, maybe I should use:
* Mills ww
* or, say, Holco metal film ... which I use in other places in the circuit?
Or - as I understand higher wattage resistors have less noise - use 1w metal films?
The other place in the circuit where a series res is used is between the Drain of the 1st gain stage JFETs and the passive RIAA circuit - this is 47K.
