650 PM Speaker Replacement
#4

So here's my dilemma; I have a Philco 650 speaker that has a badly damaged cone and an open in the output transformer (P/N 32-7078 ) primary. I looked into replacing the two components with a PM speaker and associated output transformer. Cost is around $80-$100. Another option is to rewind the transformer and re-cone the speaker. Cost, about $70. Questions arise in rewinding the transformer: 1. How do I open the transformer core? 2. What can I use to remove the paper coverings on each layer of the windings? 3. Is the primary wound on the inside, outside or intertwined with the secondary?

Does anyone have this transformer or a good replacement? I don't see going ahead with the rest of the radio till I get this resolved. (What would Marconi do?)
