The 17GP4 is a real oddball, AFAIK only used in an RCA. The 17CP4 is a more common magnetic focus CRT used in some Admirals RCA's and others.
You can use a 17C instead of a 17T but needs a magnetic focus unit and mounting brackets.

In a related story, my dad used to carry a small tool in his pocket for fixing intermittent or dead elements on the old CRTs that used the old phenolic bases, from B&W right through the 21AP color.

It was a small rectangular piece of brass (like two inches of a wide carpenter's pencil) with a hole drilled down the center just large enough to slide down and over any single pin of the crt socket. There was a thin slice opened on one side of the tool and a handle that would fit in the slice and pivot from the end of the tool.

So dad would slide this over the wayward pin (tight fit) and flip the handle into the slot and press down. What it did was crimp the pin, and the tight fit of the tool meant the pin kept its overall round shape.

I have that tool somewhere. If I can find it, I'll post a picture of it.

A Burns Perfect Pin Crimper. I had one years ago.

Pins are fine... filament is toast... Tv came with a brightener attached, Extremely dim picture, and ZERO emissions.. Filament gave up the ghost during a gun cleaning attempt.. Tv had sound and static when rotating tuner. and V&H sweep from what i could see.. I have frenkensteined CRTs before, this is my first metal attempt.. I was told the GP4 would fit the bezel the best, dont wanna chop up the bezel if i can avoid it..

I don't think that's possible though since it has UHF and the inspection tag says Sept, 1953.

It's a 17" set in a black bakelite (or is it plastic ?) cabinet. Rather light since there's no power transformer.


Odd that his dad would get a set with UHF way back then. Did they have UHF in downstate IL back then or could he have picked it up from Chicago ?


It has a TS-410 chassis.


Uh-oh, that doesn't look good
Sure enough - the 17HP4 is dead


That's a shame it was replaced with a Sylvania Silverscreen 85 in 1963.
The Peoria market was a UHF island, and the Rockford and Champaign markets had singleton VHF stations with multiple UHF network affiliate stations.
