I just got a MFJ 259 [ not b ] , and found that the band switch , is making intermittent contact , no reading until a slight pressure on sw.
So looking for suggestions , fix myself , source for info , parts ect.
I'm going to start with a little contact cleaner .

If the bandswitch is the same as the one on the MFJ 249, I have a backplane board from one that the counter module went bad on. Has the capacitor as well as the switch, 6 position, up to 170mHz. Say, $5 +shipping?

Spaying is first step. How could you go wrong for five (5) bucks? 73 Joe W4CBJ

Well the cleaning worked , switch / meter reads steady .
But now no reading on the frequency counter " b " on LCD .
