So this is why it's all very confusing.
I'm pretty sure that after the components are checked/replaced (wax/paper caps, resistors as and where, etc), testing Valve Radios without a Variac for gradual introduction of current is generally frowned upon, not least because just plugging it into the mains could cause severe risk of damage to components with associated smoke and possibly bowing the mains transformer. The limiter (for me) would work is a visual indicator in conjunction with the meter to be able to spot any open or suspicious components.
