"I recall to being very puzzled that one side of a heater filament circuit was showing continuity between LT+ and chassis. At least with the valves out I'd have expected only LT - to be at chassis potential and LT + to simply be a direct feed to the LT + terminal."
If it was a series connected filament valve battery receiver then don't forget that most of the filament pins will be ultimately shunted to chassis via a series chain of resistors.
