Dave,

I remember trafos with tar myself. But as you say it was a bit smelly.

I think wax is interesting. It is in fact low priced. Concerns are a low
melting point and possibly conductivity. But I think I will go for a
test on this.

Thanks & Regards
/Ake

Ake,

Some of the glues become (noticably) conductive over time (and
temperature).  The origin of my suggestion about waxes came from the
fact that boards and individual components were frequently coated with
waxes (beeswax maybe?) as conformal coatings in the days before silicone
or acrylic conformal coatings (say, the 50s and early 60s).
Additionally, I recall that core and coil neon light transformers were
often encapsulated in tar (quite a mess and smelly too).

Regards,

Dave
