And I saved myself from a blunder by being a bit slow: when disconnecting the chassis it looked like it is soldered to the tweeters. I was about to start cutting and labeling the wires when upon close examination I realized they are, after all, connectorized, each being an individual single-pin connector. So I pulled them out, labeling with a P-touch as I went.

What prompted me to look closer was the notion that 38-690 is way too expensive and upscale a radio to not have a connector for the speakers, and it especially made no sense if the big one is connectorized and the small ones are not.

Although in Philco 16B, which is supposed to be a high end radio, the speaker was soldered without a connector. While a cheaper 20, or 70, did have a plug.
