Question #2:
This radio has what Philco called a "Fotometer Visual Tuning Indicator." Here is a description of how it is supposed to work, from a 1939 Philco booklet which includes listings of their Philco-Tropic models:
Only, in my set, the brilliance of the light increases as a station is tuned in, rather than decreases
Is this a problem, or a mistake made by Philco in their description?
Have a look at the partial schematic below. You can get more detail by looking at the full schematic (link above), but this should also be helpful.

Quote:Fotometer Tuning Indicator - Improved visual tuning. The brilliance of the light decreases as you more accurately tune your station. Effective, simple, quick. No looking for an indistinct line (Models 750 and 770).
