Philco 77
I've got a Philco 77 in which someone replaced the speaker. It appears as if it's missing the field coil and is missing the center tap on the input of the output transformer. They somehow connected the wires weirdly, they hooked the outputs of the output transformer and the voice coil in series and then hooked that up to where the Field coil should be. Would this have worked?
The resistances of the speaker are as follows ~Voice Coil 5 ohms ~Output of transformer 0.5 ohms ~Input of transformer 855 ohms Here's a picture if you're as confused as I am 20181011_212205.jpg The blue and green go to the input of the trans The yellow and black should go to the field coil
