The CK3000 is a Telematic-made jig, IIRC Be careful with subbing across to an RCA. Some cables work fine, but some cables, loads and adapters are w-a-a-y different. Most I've worked with had the yellow tags hanging off them, warning you to use only with a Sylvania or Tele-matic jig.
What you need most to find is the molex to octal adapter that came with the 10J106, or a pinout to make your own. My memory is that is was a straight arrangement - pin 1 to pin 1, pin 2 to pin 2, etc. RCA always used color coded wires, following the EIA color coding, same as the resistor color code for 1-10, but using tracers after 10. My convergence extender cable is just that - all the colors match up to the pin number. Rca's one exception was with the Chipper Checker - the wires were all the same color
for some reason.
The convergence and yoke adapters - good luck finding any pinouts for those. RCA kept that info out of our hands - they needed to sell adapters to make the jig program worth their time. On my one and only visit to the local Sears electronic service center (to pick up some regulator SCRs for a Sears/Warwick set), I noticed they had a huge black wall organizer for their RCA jig - 30 or 40 boxes to store their jig adapters. Never saw a jig - just the mailbox-looking organizer with all the RCA boxes and loose adapters in them.
I'm not sure if the 10J130 is the adapter or not, but here are some photos from an eBay listing - Photo credit:eBay
