Time to check out the speakers. The originals look like the spent some time in a very damp environment - possibly even submerged. I also found that he voice coil in the smaller speaker is clogged up with rust and dirty and doesn't move much.

Luckily, I scored a set of Wheeler speakers on ebay a few years ago that have identical dimensions and wiring. Also, the resistance matches the Philcos very closely except for the output transformer secondary plus voice coils. I get 6.5 for the Philco and only 0.3 for the Wheeler. I think 0.3 is about what I've measured in other speakers.
The Philco values are in black and Wheeler in purple.

So much as I'd like to keep the set all original, I'll go with the Wheeler for now.
