I mean percentage deviation from nominal value(+-%), not resolution. Look at his manual or specifications.
If those values are close to real, they are fine. Waiting for pictures of finalized build.
Why my shunt output voltage is not steady and it going up in the first few minutes after start ? Is that normal ?

Yes, its the Tc of its K170. A bit more than others because GR. Set it for after say half an hour.
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 🙂

Use 105 C part, mount it underneath board if you got space to stick out the other way, or mount the MOSFETS parallel like in power amps or many DCB1.
Hi
could I use smaller coupling cap for C7 (V1102F0), it is looking into R8=1M parallel to 47k on the input of my line preamp (grid to ground). I think 0.47uF will give me around 7.5 Hz corner freq. which should be low enough.
Cheers

Give it 1uF because C3 does some pre roll off between stages, and 0.47u cuts too early in that situation.
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

I did not like non bypassed pio there, sounds thick. Get a 47n-100n Mundorf that is cheap enough because small value.
Obbligato Gold Premium and Mundorf no oil simple Supreme seem down to earth priced in 0.1u value.
For MKP I recommend 1st choice Auricap, now 40% off PartsConnexion (no commission) 0,1uF 400V or 600Vcapacitor_film_auricap.html
