Rca 6T54
Well looks like I picked up another set, I've never worked with metal cone CRT's before. (but free is free) Someone correct me if I'm wrong, but the whole metal on the tube (16GP4) carries the HV, correct? Seemingly a little dangerous if you ask me. Anyways, assuming this tube has a life left in it, should I seal the tube with anything? I've heard that the metal-glass junctions are the weak point in any of these tubes.

Yes, the whole cone will carry HV. Some sets had a plastic shield, but not all. It sure will command your respect! I've had at least a half dozen metal cone sets plus various spare tubes and I don't think any of them had gone to air.

Thought I would post some photos since I was able to haul this behemoth onto my workbench. This thing is absolutely massive for a "tabletop" TV, most of the other 6Txx's I have seen were freestanding floor models.
I'm also happy to announce that the 16GP4 was coaxed back from the dead, now testing borderline good. I'm hopeful that this will produce a nice bright picture when it's completed. More to come soon 20180706_221657.jpg 20180706_223153.jpg 20180706_180902.jpg 20180706_215334.jpg

Hi.
I recapped a RCA 6T65 last January. It uses the same chassis most likely, a 47A. The chassis was known to kill power transformers, deflection yokes, and horizontal flyback transformers. In order to get my set operational after the recapping, I ended up replacing the flyback and yoke. I had to replace the width control also. You may want to check the power transformer windings and flyback windings before you start your recap. Ed |

I've seen a couple of those and your mistaken. They were not consoles, but rather all table models just like yours...There was a matching factory stand that was very popular (most sets seem to have it) which gave the illusion of it being a console.

It's intresting, almost every non RCA tube that had been replaced was bad and every RCA tube was good. I've never noticed that in sets, but do certain tubes tend to wear out faster than others?

Glad you posted the pictures; I'm not good at remembering chassis numbers. I have one of these, special as it belonged to my great-grandparents. Outside of assuring the crt is good I've not touched it. It also has the separate stand.

Detector diodes, RF/IF pentodes, the oscillator and mixer in the tuner, etc, were all taxed much less in use and tended to last a much longer time in service. One of my 630 clones has what I believe to be all original tubes; except for the HOT and the HV rectifier. |
