Hallicrafters T-54

Oh yes, I forgot ... the original purpose of the whole thread!

The plate cap of the HV rectifier is awfully close to the lid of its box.
Is that safe? Should I install insulation? Should I go to a perforated
metal lid for cooling?

Or, I could install standoffs so the lid had 1/4 inch of
clearance both for HV purposes and ventilation.
