The horizontal yoke leads come out of the jig on pins 4&6 of the octal plug. Vertical is pins 1&2, with a jumper between 7&8. Use an octal socket and some leads with alligator clips or flat slip connectors on the ends to make up a yoke adaptor.

With the above information, you will be able to make any adaptor for any tube chassis to hook up to this jig.

I have the pinouts to make adaptors for the CTC 4&5 chassis, as well as later tube chassis, so let me know if you need them, and I'll post here. All you will need to do is find a plug that mates with your yoke socket, or a good improvisation.

BTW...Older Sylvania, Telematic, RCA, and Dowd jigs are the same.

I hope this helps!

Thank you for this extremely useful information! The problem of interfacing my CK3000 to a chassis for a Sylvania 31C304M that I'll be restoring soon seems to have a solution now.
