Model 90 Speaker field coil repair
#1

After spending $$$ to get the speaker cone replaced, I've determined there is a break internal to the field coil (and not at the lead connections--I checked that first). So I'm faced with the task of removing the field coil bracket and freeing up the coil so I can rewind it. I understand the model 90 coil retainer is press fit but I'm not sure how to go about removing it. Any suggestions on disassembly and rewinding would be appreciated. I understand the field coil resistance to be around 3100 ohms. The voice coil is fine, it shows .7 ohms.
