Hi Everyone! I just completed two Cadet VCOs because the first one I built has some of jitter when in vertical mode. It also looks dimmer / not as sharp as the horizontal, which is stable and sharp. I built the second one later to see if I may had made a mistake in the first, but the second one has the same issues. Did I do it wrong twice?? 
My first thought is that it might be the self-made flying sync bus cable I made, but horizontal mode and all other modules using the sync cable are rock solid. Both Hsync and Vsync look ok on the scope. However, I can influence the vertical jitter by touching the sync cable. I cannot influence the horizontal. I can’t see any influence from touch looking at sync on the scope.
I have all ten Cadet modules in a Doepfer A-100 LC6 case with PSU3 along with some makenoise modules. I’ve had the VCOs close to and away from the PSU. I’ve taken all other modules out except I II & III. No difference. If I had to take a guess, I don’t think it has to do with the VCO core, as horizontal is fine. Could it be switching / coupling to Vsync on page 3/4 of the schematics here? 
I made some test recordings and put them on vimeo. The sync switch is off in each case. Take a look. Anyone encounter this behavior? Any thoughts about where things are going wrong? Thank you!

Again, any thoughts would be appreciated. Thanks, all!
P.S. I tried to post this to the LZX Community Forum, but accidentally only posted the vco test video and got blocked. I reached out to the moderators, but there doesn’t seem to be a lot of traffic over there these days. Waiting to be unblocked…
