I have for sale a few populated pairs of to247 cascode pcbs that can be used with those lu1014 that you are stashing 🙂
I can offer also the empty aluminum pcbs on which you will solder the smd jfet, a gate resistor and gate protection diode.
All gets joined with wires, I have bad experience with strip connectors and aluminium pcbs.
It lets you adjust the vds of the jfet with a trimmer.
30€ for 2 populated cascode pcbs
10€ for 2 empty alu pcbs
Schematic looks like this
Modules and alu pcbs look like this. The wired module is not for sale.
I am getting great sound with these in my Gaincore amp.
