Thanks for the reply. I figured it was shot with those bizarre readings. 
I tried prying off the back a couple days ago. I didn't want to completely destroy it in case I have to reinstall until I find a suitable replacement.
I did see all the cheap 10k pots available with most rated at .25 watt or so. 
I'm hoping another Phorum member is out there that did find a capable replacement and can assist with vendor and part number.

Agree with your novelty comment except I've actually used the feature for decades.
It's whenever the Mrs. is within earshot when I'm tuning around the world.
She always hates the "noise" and with the working QAVC I could back it way down. 
I always find the in-between station noise part of the charm!

Good luck with your latest 16B build, I'm sure it will be another great one.
