The parts list says, field coil speaker part number 62 on the model 39-40. Part number 57 is cone and voice coil. I have read here on the phorum about replacing field coil speakers with permanent magnet speakers. I would be kind of guessing it's a 4 ohm voice coil. Thinking to replace the field coil with a 1000 ohm power resistor at 15 watts. I haven't done this before, but I've been reading about it.
Thanks for your help,
Dave
