That 35Z5 damper with hum control is another oddity

Wao. Talk about engineering overkill. Sorta like Muntz in reverse.

I'm very impressed!
Although I'm not a fan of duct tape in permanent construction.

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.

Does anyone have an extra of that set they'd like to get rid of? That is the niftiest set I've ever seen. Even a hv regulator. Wow!

[Bill Cahill]

Gee. I've never seen re build work like that in my life. It is utterly magnificent.I couldn't do work like that.

Hey Ed, nice work on the Motorola. That was a pretty incredible undertaking rewinding the vert yoke coil. I'd probably of had that thing tied in a knot before I got it back on the yoke form. CRT picture is shaping up nicely.
