Thanks OZ4
I have zero experience with ripping apart a speaker to check the field coil, i have come to the conclusion to leave this to the experts that have the proper tools to complete this task, therefore I am in the hunt for someone in my country (Canada) that has experience with re-winding field coils, as I do not want to throw the speaker away as another member had suggested.
Now regarding replacing with a PM speaker, i have done some reading and it looks like using two equal value resistors in series that would make up the 1140 ohms needed for the replacement of the FC would be better for heat dissipation with an electrolytic connected to their junction with the - going to the - of the other 2 electro's would be great for reducing hum and may sound like a plan, am I on the right track here?
and if I can use the current output transformer (primary of 6,200 ohm and Secondary of .89 ohm) what type of impedance of PM speaker would I need?
Thanks in advance!
