Let me apologize in advance since this post has nothing to do with Philco radios or any vintage raadio.
I'm restoring a Gibson GA 6 F guitar amp with a Rolla field coil speaker. The speaker has the usual field coil winding and another winding that is connected in series with the speaker voice coil and secondary of the output transformer. Can someone tell me what the purpose of this winding is?
Any information would be greatly appreciated.
