Hi Salas,
i have built your phono stage to fet. For the riaa i have used:
Resistor metal film 1% 47K,
Resistor metal film 1% 6.8K,
N°2 Cap 47n + 1.5n to 5% (i measured 46500),
N°3 Cap 15n + 330p + 100p (i measured 15300).
This value are correctly for accurate riaa?
Many thanks
If those values are close to real, they are fine. Waiting for pictures of finalized build.
Since I didn't catch up the latest BIB GB I'm proceeding with Shunt 1.0.5 from pdf P2P.
Here is my PRELIMIARY layout... (Don't use it without care !!!)
Board will be mounted vertically with Q1&4 bolted to case bottom.
The only thing that bothers me is that C4 is too close to Q4 (heat..) or it shouldn't.
Comments please

Minimum current and size of R101?
In the BIB guide rev. 2 it says that minimum current drawn is 100ma and I am going to use two regulator in driving the Salas minimalistic NFET Riaa. I have to be certain, is this so or can the current use be lower like 25mA/20% over load consumption?
With regards
Martin

For MKP I recommend 1st choice Auricap, now 40% off PartsConnexion (no commission) 0,1uF 400V or 600Vcapacitor_film_auricap.html
