I have 20 console. Was the first radio I fixed.
I would look at the Field coil of the speaker. I think sparks came out of it. Disconnect, measure resistance, see if it is in accordance with the schematic's value. Unlike in many other models the field coil here is not used as a filter and is simply placed across the rectifier's output. The resistance should be 3,100 Ohm.
It is possible the wire of the field coil is simply making a bad connection.
