"I have no idea where Joel is coming from as the RC coupling is pretty wide range in the amps I have seen, and, at least by 1940, the bandwidths are in the 40-10kHz range, -3db (fram manufacture specs). "That's an interesting point, though I admit I only have a partial grasp of the idea Joel mentions. But I would also point out that we haven't even talked about the tolerance windows that parts of the day exhibited. 20% tolerances and higher on big electrolytics. Did anyone expect anything like precision timing from RC networks built parts with such high potential deviations? Maybe I'm missing something here....
