Hi All;
Partually, it depends on what you have for test equipment..
For starters, If you have an ohm meter, then free up one lead on each side of the coil and see if it shows any ohm readings.. For the moment it doesn't matter what the reading is, but that you have one.. If you find out from further test that there is still trouble, then the reading will make a difference..
Next, if you have an audio oscillator or a source of audio.. First check that the speaker works and ohm it out.. Then connect the speaker back to the Transformer back to the speaker.. Thru a capacitor pass an audio signal, You should get some level of sound, it may be barely audiable or quite loud.. The main thing is do you get any sound from it..
As another alternative, With the Cap you can use it to prod the filament 6.3 volt AC line for a source of 60 cycle hum, then go from the speaker back thru the transformer until you find where the signal disappears..
THANK YOU Marty
