Another Casualty

[Bruce]

I think it's more that you just reached the end of it's service life.
Nothing lasts for ever.  Vibration and heat will kill eventually kill the
best of electronics.   FWIW, some of them I've run at continued WOT under as
high as load as I can, and 110dF is a *normal* operating temp..

quick prom changes.  This probably didn't help.  Yesterday I put velcro on
the cover so I don't have to operate a nut driver to take it off.  Maybe a
fan would be a good diy project?
