Default Re: Cossor 524 rustling noise on FM

Does it have - anywhere - those ceramic trimmers that are made by metallizing sprayed direct on the ceramic base and the rotating part?. They are sometimes orange.

Problem is that the metallization-to-the-connection-points breaks downand can cause strange rustling/fizzling effects.
