Hi again
After a closer look on the spec, it seems i got it wrong the first build.
I just tried with the reversed/correct pinout on a fresh LM334, but its still not working.
A dead short between the probes, shows 60mA on my DMM, the last build showed a 140mA
I've installed this LTSpice and replicated my circuit there,
and my simulation is nearly identical to yours.

hi,
The problem is I dont have a LM334 on the shelf so that I could actually build the circuit.
The LTS sim did show if the series diode was o/c then the current increased, check the diode.
