Izzy,
Restored, that is a nice alignment meter. A "visual" AC ouput meter. You hang it on the output tube and watch for the audio peaks when aligning the compensators. You connect it across the plate and cathode of the audio out tube or to both plates of a P-P set.
Was introduced early 30s, I believe. Last offered in Philco Parts Catalogue in 1937.
