Hello, I have a Philco speaker where the voice coil seems to be frozen in place probably by rust. I was hoping to remove the cone and maybe clean out the space if possible. The basket appears to have a metal frame around the perimeter. Is this frame holding the cone to the basket sans glue? I was thinking bending the tabs back and remove the frame and hopefully remove the cone. Has anyone attempted this? The cone is in perfect shape. The picture showing the spider shows the cone being out way to far as well as the voice coil picture.

This speaker is from a Philco 91 (code 121) single speaker. I don't know what the readings on this speaker should be but the field coil seems wrong at about 44 meg. Is that bad? The output trans reads 380k ohms and .6 ohms.

Further investigation. When I remove the field coil wires from the output trans posts I get 22 meg. On the primary side of output trans I get 377k. Trans has a center tap where one side I get 360 ohms and the other side I get 376k ohms. Does this sound right? The center tap connects to one of the field coil wires.

Thank you,
Dan
