[R-390] MFP Problem

[Curt Nixon]

I see one of the responders mentioned transformer varnish..I think I 
might try that as oppsed to shellac, just because you know it isn't 
going to attack anything and it has good dielectric properties.  Shellac 
thinner is wood alcohol..not the is0propyl kind, the other, fuel  stuff.
