...no it was for thermal reasons: being close to the tubes meant a lot of
radiated heat and the white paint was for reflecting the radiated heat away
from the transformer.

Hi Jeff,
I believe the Bill Orr series of Radio Handbooks espoused painting filament
transformers that were to be located INSIDE THE AMPLIFIER ENCLOSURE a flat
white...this was to reduce some ill-effect(s) from the close proximity of
the unit to strong RF fields (the exact reason escapes me just now).
Other than that, why not re-paint them...?!
