Oups ! RTV did you said Tom ?
apart from the mechanicals : research electronic grades before you get more
problems still in long term on chem side .
Some of the acids present, and other compound segments are real field
tickers if memory serves me right .
But you likely did that ; so to the mechanics (not the wiring up gas stoves
stuff) :
From the sound of it you have a snowflake chance in hell of finding the
spacer ;
you have plenty of room between the leads, and doing a lot of tedious work
(paid for?) :
When we've had this one in past we gave our girls a
teflon/nylon/somethinglikethat pointer to quick check/reshape the wires ;
and that was it . Common thing ; as winders are generally not that fussy
about terminations routes .
Once (past life) I've had 40 winders on one of the floors and 3 yards dia
dip tanks for trafos of all sizes :
used to be fun before Peoples Republic took over .
Did read some US strategic industries platforms studies > interesting
reading = true we're gettin' the stuff cheap ; but ...........


See you
