Looking for a replacement or way to fix my smoked turret encoder on the CHNC II

What is the wsum mentioned in that thread? All these acronyms aren't for newbies to follow.

'wsum' is a HAL component in LinuxCNC:

Try Acetone, or nail polish, preferably in the 10-15% range.
Be aware that if you do find that concentration, it eats almost everything.
Nail polish is pretty safe to try, and if you get it on other stuff just rinse it.

Got it. I started with a hair dryer and though it was working but realized when I just slowed down it's grip strength was just barely more than tensile strength so it peeled off going slow.

Unless you guys surprise with your ability to read what was read in this blackened mess it seems useless until or if I get a schematic. I did see remnants of a C before the 1 on the edge. And following the way other labels are on that pcb, the 2 below that suggests to me there were 2 capacitors( for the C, right?). 

To me this looks like a common shaped capacitor, as little as I know about them.
