B+ is about 150v, but between 120 and 160v will be good.(current 2.8mA).
This B+ comes from the MM section and is already very well filtered with CRCRCRCRC. If you only want to use the MC pre you need a good stabelized B+ and regulated heater supply.
Sorry i do not sell PCB's, but your free to use the PCB film design.

With the 6n17 you have to redesign the schematic.
The 6n16 has very low microphonics and noise. The 6n17 is probaly worse because it has much more gain.
Sorry,I do not produce any PCB's, maybe there is some one near you. Or else look and ask at zelfbouwaudio.nl.
The PCB designfilm is in the first reply of this thread.

thanks.
What is the minimum distortion you can read with the instrument?
It says that distortion of the sine wave is <1% which is a bit vague ahahahahah!!!
That is the maximum distorsion of the generator.
Signal distorsion i do not know yet how to measure. Total harmonics distorsion i measured on the Mini-Me.You have to measure the harmonics from a 1khz sinewave, count and measure the harmonics from 0 to 20khz and then calculate the THD.If you have measure the noiseflloor then you also can calculate THD+N.
Picture below is a harmonics measurement.
