[Elecraft] KPAIO3 modification - E740287

[G4GNX]

I'm in the process of upgrading our club's K3, new synth, DSP and a stack of 
small mods.

I've come up against an issue that's causing me some confusion. The mod for 
the KPAIO3 consist of a small electrolytic capacitor soldered to two pins on 
the KPAIO3 module. I have two versions of instructions, one dated April 13 
2016 - Revision A and the other dated August 10 2016 - Revision B. I presume 
that Rev B supersedes Rev A, so I should follow Rev B?

The images on both sheets appear to show the KPAIO3A module, but describe 
the KPAIO3 module, so I presume for the purpose of modding they're the same, 
however the Negative lead of the new capacitor is shown going to different 
points on the module, depending which instruction sheet is viewed and 
looking at the trace layout on either, this doesn't make sense. Besides 
that, the trace layout on the module that I have is different to both of the 
paper descriptions.

Can anyone shed any light on this conundrum or know if any addendum has been 
issued?
