Fortunately these jFETs are manufacturer in a virtually symmetrical layout.
The D & the S can be swapped and the device will probably operate the same way.

With the dgs PIN out, you can insert these jFETs back to front and the circuit should still operate normally.

It's the ones where gate is not the centre PIN that cause build problems.

Yeah! even some well known companies do it that way to save space. Bryston has some amps that way!
