Yes, the A-112 consists of an octal plug having four color-coded leads terminated with male blade connectors. Red and blue connect to the female blade connectors on the red and blue horizontal yoke leads from the chassis under test. The yellow and black leads connect to the corresponding vertical yoke leads (yellow and yellow-black). If the chassis has a fifth (usually orange) yoke lead, this lead is left unconnected when using the CK3000 (it normally connects to a fifth terminal on some sets' yokes, which is the junction of the two halves of the horizontal winding, when used). The octal plug of the A-112 then connects to the mating octal socket on the B-207 yoke extension cable. The Molex plug on the B-207 should be plugged into the Molex connector marked "Deflection" on the CK3000 patch panel.

Likewise, the A-113 CRT adaptor will plug into the CRT socket end of the B-230 CRT extension cable. The Molex end of the B-230 then connects to the Molex connector marked "CRT" on the CK3000 patch panel.

The red and black (Anode and Ground) leads will then connect to the Anode and Ground connections of the chassis under test. For "hot chassis" receivers, the chassis under test must be powered via an isolation transformer to minimize AC shock hazard.

Another adaptor having an RCA plug on one end and alligator clips on the other should be included with the CK3000 in order to connect the speaker leads of the chassis under test to the "Audio" connector on the CK3000 patch panel.

For all "roundie" setup codes (designated "1A" through "1M" by the manual's setup tables and chassis-setup cross reference) and other setup codes for tube-types chassis, the octal plug marked "YP-12" will be connected to the Yoke Program socket on the CK3000 patch panel.

Most of the "roundie" setup codes use Convergence Ballast "CVL-1" while some will use CVL-2, CVL-3, or none. For many chassis, the designated Convergence Ballast plugs directly into the Convergence socket of the chassis under test. Some models use an adaptor between the CVL-x ballast and the chassis Convergence socket (most Zenith "roundie" chassis use the CVL-1 ballast paired with the CC-19 adaptor).
