Hey: Guys.

I'm fixing an old Cobra 21XLR & that damn glue that they used to hold part still like large capacitors crystal & so on has ate the legs off the three crystals in the radio.

I need a 36.570 Mixer crystal.

Anyone have a good new or used one ?

Let me know please.

Thanks.

Bruce.
 

pretty much any UPD858 three crystal AM only radio will have these crystals in them.
might be cheaper to find a junk unit on ebay than the actual crystals themselves.

here is a list of radios that are the same as yours so you can search for them.
yes, they may have glue issues as well im afraid.

    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
