Default PCBPCBs for Nelson Pass‘ CSX1 SONY VFET amplifier

I posted a PCB layout in the thread „Article – Sony VFETs part 1” which seems to find some interest. So I’ll offer a small run of those boards.

Technical specs:

Epoxy 2.2mm thick with double layer 105µ copper plating, solder mask and silkscreen.
Size: 240mm*107mm per channel
On board there is the VFET circuit plus the Gate BIAS supplies and the regulated main supplies It is provided for either the wired or the print versions of the Jensen transformer.
The transistors are mounted on an L-profile which allows to fix the complete unit directly to the heat sink.

Small auxiliary boards for the BIAS supply transformers and their rectifiers will follow soon.

The price of a set of the amp boards depends on the total order volume. I’ll keep you informed.

I could also supply proper cut-to-length Aluminium profiles 240mm*40mm*40mm, 5mm thick, on request.

Orders are welcome. Please send PM.

The actual price will be around EUR 30 for a set (2 boards) + shipping cost.
