I've been restoring this Model 43, and have come up with a problem.  The tuning capacitor, once I turn the dial past 1050 kHz or so, produced a consistent howl across the rest of the tuning range.  I've done everything I know to do, to get the plates centered, and they now seem to be.  Reception for the small area of the working tuning range seems improved, believe it or not, but the problem remains.  I don't know what else to do.

Is it possible there could be a crack in a rotor plate, or some other irreparable flaw in the capacitor that would cause this problem, assuming none of the plates are too close?

I'm assuming that would mean replacing the capacitor.  Does anyone know where I might find one, or how and in what forum or media to post the want ad?

Thanks so much for your ideas and suggestions!
