painting tubes black for heat disposal???
Dull, black, heat resistant paints
have been used to help cool engines for ages.
It would be cool (literally) if one could
spray and heat-cure unshielded tubes
and improve their heat-shedding
Is there any indication that such paints,
or some vacuum-tube specific types,
would help keeping tubes cool
by improving heat radiation?
I'd love some factual info, if it exists, or educated guesses,
rather than uninformed blind guesses,
as I am awfully good at doing uninformed blind guesses already! :-)
