I need the center bottom knob for my Philco 620. Does anyone have one?
The speaker in it has a good field coil and audio transformer, but the cone was completely gone, and I ripped out what was left of the voice coil. Unfortunately there is rust in a portion of the gap around the pole piece. Do you think it can be reconned, or should I just try to find a replacement speaker. The mounting bolts show in the front, and the speaker is round, but with square corners, so I can't use just any round speaker to replace it.
