Hi Waveydipole
So is that a fact the 2N3819 JFET can be used either way round, with equal efficiency, the only pin which needs to be specific is the gate.
Wow that does seem strange.
The project I am working on is a Minimod TX, Phil G4SPZ has been sent me a photo of one he made so I will be fitting the JFET in the same way.
The positive supply is fed to the JFET by the red and green wire.
Thanks
Mike
