I sprayed contact cleaner on a dirty mic switch and it made the switch so its dry and does not move freely..and it is not completely disengaging contact......any ideas how to fix this?
 

Try a VERY small amount of a non-conductive lubricant. Dielectric grease - sometimes called silicone grease.

Do NOT use lithium grease!

    Hello gentlemen and Ladies. I have the dreaded RCI-2990 receive issue where my radio gets distorted when people get close to my location. I found the C90 Capacitor, but I can not for the life of me find the C89 capacitor. Can or does anyone have a picture of the exact location of C89 ? Thank you in advance, Wes
