These are a couple of pictures with the rebuilt 16AP4A that came with the set. First is with the focus coil disabled. The second is with the focus coil connected to a separate power supply.
The crt wouldn't focus so I checked it out of circuit. I spent a day going over the focus circuit, everything matched the schematics, even the red and blue focus coil wires to the plug connector. This set I found had the wire connections inside the focus coil itself backwards.
I also used this chassis to test another 16AP4A crt today that came out of a Motorola TS-52 chassis I bought in the late eighties. Those are the last two pictures.
If any one else ever comes across a the TS-16/16a chassis, you can find an entire description of its' circuits starting in Riders Volume 5-8 for Motorola. I used a Teleaides for the schematics, better than the Sams for this chassis.
