RCA 170PO63 Portable (KCS126 chassis)

[Radiotronman]

I have a portable set with handles on the side instead of on top. I think these were called "sportables" by RCA. They're excellent performers and made very well. Those are the correct knobs on your set. You can see mine below.

That's an excellent set. I have 3 of them, red, brown, and black. Also, spare parts if you need anything. I rented the brown one to the movie makers of PARKLAND.

Did a little more poking around, and have a little more confidence that the fly might be OK, I checked a couple windings and it's not open. CRT is a toss up, it's pretty weak, even after allowing it to cook for a while, but I haven't tried rejuvinating it yet - I'll see what kind of picture I can get out of it before I resort to that. I know I have spare rectifier tubes, just need to find which box I put them in...

Anyone have the schematics for this?

I'll bet on the fly being good. A little drippage doesn't generally mean anything unless it's accompanied by a distinct scorched smell (from the old servicing adage "the nose knows")

I never worry, when I see a cracked tube, I just try another one.
The CRT might come back. It was probably dormant for 40 years.
I like that chassis a little better, as it uses a 5U4 instead of a voltage doubler, like the next years models. I always admired the horizontal hold control design. One of the early multi-turn types.
The set you have, has the metal back. The next years models had a back that was made of some funky, crumbly plastic that didn't stand the test of time.
