Hi Paul,

I myself have no experience (successfully) using OBIT's.  My only ill-fated experience was when I was a total newbie and thought I could series the outputs from two OBIT's.

I can't think of any reason OBIT's would be intrinsically inferior to NST's.  Both have similar construction and specs, and both are current limited.  I would like to think (HA!) that OBIT's being in a more critical application, might be built a bit sturdier than something that just needs to light a sign?  Perhaps it's that the used OBIT's that I and others used were pulled by a serviceman for good reason, and may work just fine on a good day, but...?

BTW, 9kV@50mA sounds unusual for an OBIT.  Every one I've seen is rated 10kV@23mA.  OBIT's typically have inconvenient HV terminals, designed to be attached directly to the oil burner.  Are you sure you don't have an NST?
