Canadian Philco #366 (60B USA). If I insert an audio signal just before the Type 75 and Type 42 tubes the signal appears at the loudspeaker. Inserting the signal at the volume control does not get to the loudspeaker. The radio was working, but a small pop came out of the peaker and it stopped working. Band selector switch tests okay, but quite stiff and is set to AM Standard frequency. If not a tube, then what?
