I've never seen the RCA service literature for the "Lyceum" sets. It wasn't included in our standard RCA literature, had to special order it. I know one model, JM-897W was a metal cabinet CTC-38 using chassis version number CTC-38XE. The interface circuit board for the AV connections had an RCA part number of 130429. There is a Sony black and white set, model CVM-2300U, that is covered in Sams Photofact set number 882, folder number 3 that appears to be an Emerson tube chassis TV with a Japanese sourced AV input board using 6 transistors and a relay for selecting regular TV or the "Videocorder Socket" it has.
