Simplistic NJFET RIAA

Hi Guys,
i would like to know if you have a better sound with a bypass cap on RS in input stage? Thank you! Maxpou

What phono are you using, same mine 63dBs, if yes following Salas advice I bypassed with a 10nF VISHAY-RODERSTEIN MKP-1837 Metalized Polypropylene Film Capacitor in parallel to C10 4.700uF HQ 10V, incredible perfomance in highs, now I'm other new member in the list "can't live without them" 🙂

Hi merlin,
I have the same phono of your but on my schematic I don't have 4700uF on RS and I would like to know if you have a big difference with and without 4700uF? Maxpou
 
Because in the moment of building only had severals LSK389 & Salas choose these value tor (I suppose) get the gain asked for me.

Possible next Simplistic will be only with SK170 I have on hand a batch of 100 pieces matcheds but the gain will be 60dBs I have the schematic posted by Salas.
 
Hi Guys,
PCB with suggestions of massimo. Maxpou
