I found this on the Tube Cad website - https://www.tubecad.com/2015/12/blog0335.htm. It looks interesting and curious to know if anyone has tried this or something similar. I'm still a little unclear as to how the part values (type of NPN, resistor, etc.) would be specified but the approach makes sense.
Might not be in the less is more spirit of a Loftin White circuit but seems to address some potential concerns.
Thanks!

Ah. It's a security... I thought that it was some kind of soft start for L-W circuit.
That's nonetheless an interesting idea ! 😎

Interesting idea. It would oscillate in the error condition, though. I'm not sure that's desired. I'd probably design the circuit to be latching. Then add an add an RC to prevent accidental triggering.
