Trade or sell... 1953 Sylvania 172k CRT and chassis

I am a stereo/turntable guy... I picked up the guts out of a 1953 Sylvania
172k console. The former owner turned the cabinet into a wet-bar. I am only interested in the mono turntable. Is there any value or interest in the CRT, the chassis and the mono tuner?
I paid $50 for it all, and I would be very happy to break even....
Colorado
Tell me how to test the filament in the CRT and I will...
Pictures below...
Found out that the CRT is a 21EP4b
1-15-15 : Pins 1 and 12 show continuity so the heater is intact at least...

CRT can/will be sold separate from chassis...

It is not just the filament (though if the filament is bad then the CRT is definitely bad).
CRT cathode emission is important, you need a CRT tester or someone that has one, and is willing to lend it to you, in order to confirm CRT condition.

I understand, I have had to hunt down a person with a CRT tester to prove out a couple of Oscilloscopes over the years...I was just taking the first step...

It looks like the CRT is a replacement from 1963.... from what I found online about the 21ep4b. I still can't find a pin diagram to tell me which is the filament...

If there really isn't any interest, I'm going dive in and cannibalize it soon...

Heater pins are 1 & 12. Each side of the locating key. The 21EP4 is a cylindrical faced CRT and rather uncommon. Stromberg-Carlson seemed to use them alot.

Thanks! I'll check it out and post my findings... I am thinking about diving into the chassis (mainly just for the Transformer-rectifier) ... Is there a great reason to keep the chassis and CRT together since they are not original to each other?

The CRT is a ten year newer replacement. I wouldn't want the original CRT. The one shown is a great replacement for a set that needs one. Most collector's understand that most sets that age, would have the CRT replaced by now, so original factory issue isn't important.
Unless someone needs the chassis, I wouldn't worry about it.

Right on...

I checked continuity between pin 1 and 12, and it rung out good... so that's intact at least...

Could you please post a pic of the chassis from the rear? I'm looking for the one I had in '66 (my very first TV), but later cannibalized. it had the dual 5U4 socket assy. mounted at a 45 degree angle atop the Power Transformer (but had a 3AG slo-blo fuse/holder in one of the socket holes...

That was the one piece that I wanted from this... Just the power supply tranny with the rectifiers on top... This is that chassis, but I would want that piece... any interest in the rest?

Possibly - What is your zip? Also, do you have any of the knobs? I actually found an NOS channel knob assembly, but the volume knob seems to be harder to find...
