R2100 Service monitor BFO pot/sw

Postby xxx2fan » Tue Feb 21, 2017 5:49 pm

Hi I got a R2100 off of the bay and the BFO Potentiometor/Switch is bent and seems flakey, I turned it off and the monitor seems to be working in all other aspects. I have almost gone blind trying to identify the Pot for the BFO and figure out a replacement looking at the service manual PDF on the computer. Could someone help me out to identify the BFO potentiometer/switch and possibly a part number from Mouser or someone to replace it.
Thanks in advance for any help.

IIRC the BFO control is a simple 5K pot, no switch to it. Motorola P/N 18-80346A14. Probably NLA.
