Well I started working on the Stewart-Warner 'cube' and am seeing signs that the field coil is open. I'm only getting a reading / continuity on two of the 4 pins on the plug. Those two are going to the audio output transformer. So I'm hoping someone can give me an idea of the resistance I'm shooting for on both the field coil and audio output transformer? I'm trying to see if I can find a suitable 6.5 inch diameter speaker that I can use rather than try to rewind the field coil.

Here's a link to the schematic:

Many thanks.
