I have this old radio, uses tubes #57, #56, 2A5, and 80. The filters were open but no hum. All tubes checked good and have been subbed with good ones just in case. The speaker has continuity. There is plenty of DC to plates and screens. Recapped and coils have continuity. What could be wrong? I assume the speaker is bad but what could be wrong with it and how could I fix it?

How 'bout a make and model? Check for a shorted cap across the output transformer.

If you were reading the speaker continuity while still in circuit, you may have been reading the audio output transformers secondary winding. An easy test for the speaker, is to use a 1.5 volt flashlight battery. momentary contact across the terminals, should hear a clicking sound.

Thenks for the replies. I injected a signal on the grid of the 2A5 and got nothing. Tried a third 2A5 and bingo. Had two 2A5's in a row that were bad. Set runs fine now. Still don't know make and model number of this set.
