I'll have to visit renovated radios as some of my knobs are missing, not to mention the back.

The mask in my blond set was in pretty good condition too. Not deformed at all, just a bit crunchy

I found the time today to pull the chassis. It looks like it's complete.


Here's the HV coil. I like the primitive spot welded cover. Later versions were a single piece of stamped aluminum.


As for the underside, it's somewhat different from later revisions. Here's a TS-4J for comparison.
The two large metal HV caps are for the horizontal deflection plates.

One thing I find odd is that this set has all plastic insulated wire. Every other TS-4 and TS-18 chassis I've worked on used cloth insulated wires


All the non HV caps are Solar "sealdtite" branded as Motorola. They don't look to be very "sealed tite" anymore
