OK. Thanks JR. Looked twisted and I wondered if it was correctly installed.

So the knob on the socket refers to leftmost pin? Just wondering if there is some kind of standard for sockets.
the index on the 3 pin socket refers to the tab on the old t0-18 metal device package
That metal can tab aligns with transistor emitter (source on JFET).
As you are facing the device that is the far right pin... the middle pin set back is the base/gate, etc.
The parts have evolved a bunch over the decades from 3 pin devices in sockets.

Great info… thx. I did see that companies like Mill-Max still manufacture these but I haven’t really encountered them before this.
