[Heathkit] Frozen bandswitch

[Whitebear1122]

It's interesting to hear that others are experiencing the same thing as me.  I acquired an SB200 a few years back and the bandswitch was frozen.  It was frozen in the shaft coupler.  I was unable to turn it with pliers.  My recommendation is to not force it.  I speak from experience.  I forced the bandswitch and broke it.  I ended up having to find a replacement bandswitch.. sigh.     I have an HW-16 that I recently took off the shelf and found one of the controls frozen.  Not again…..  So I'll use PB Blaster on it.

I used PB Blaster to free up a Johnson VIking Kilowatt Matchbox frozen bandswitch.  It took maybe a week of soaking the crap out of it before it freed up.  

The PB Blaster seemed to work well.  I agree with the others, WD-40 didn't do anything to resolve the problem.  It just made a huge mess.
