Hello,
I have for sale 2 stereo pcbs done after the article in the title.
https://www.firstwatt.com/pdf/art_sony_vfet_pt2.pdf
Schematic on page 5, only what regards the front end.
I used them as a balanced preamp with very good performance.
I attached a photo of the part that is included on the pcbs.
The pcbs come with all the parts populated except the active parts in the signal path(jfets, bipolars, mosfets).
I have also the low noise power supplies that I used with them.
Sold
EDIT: attached also a thd measurement done with the same power supplies I sell here and the semis I removed.
