Batboard

I have a motorola UHF r100 repeater, and a few of the antenna preselector filters on the receiver board are bad. I was wandering if anyone has a bad receiver board where I can pull them off or know were I can get new filters. Any help would be greatful.
Thanks Dirk

Dirk,

Are the "slugs" stuck? They used gliptol on the threaded slugs at the factory so they would not detune.
