Motorola TV Part 3c - HELP!

I need some help from my YouTube friends! I have a 7JP4 picture tube that needs some serious attention. The base came off in my hand, I do not know which wire is which, and some wires and pins on the base are missing. Please watch and comment if you can help.

I also have all the caps changed out. I think I have another video in the tank showing how I did the electrolytic caps. Then, if we get the CRT base back on, we can try to power this thing up and give her the old smoke test!

BY THE WAY: I used the Permatex glass silicone for the base of the CRT. It is very thin and runny. I did not use a lot. After application I stood the CRT on its socket to keep it from running down the face of the tube. After drying it all seems to have run down into the connector base. The socket is glued on but really loose around the tunbe itself. I guess I buggered it up.

Thanks for the great response folks. I really appreciate all the suggestions and help. It sure would be great if we could all get together one day and share a beer or five! Maybe even a skype video call to talk about restorations and trade war stories????? We have the technology.

I use Permatex glass windshield RTV cement to glue by tube bases on. make sure you use sensor safe RTV and not the kind with acetone in it.

Respond to this video... Hey Bob, What do you suggest I use to fill the void that will be left on the broken side of that base cap?

[bandersentv]

@GeoN0JRJ Yeah, real high - especially for an untested CRT.

[GeoN0JRJ]

@bandersentv No sir. I let it go. I thought that was high. Was I right in thinking so?

[bandersentv]

@GeoN0JRJ Wow! $135.49. I don't suppose you were the high bidder ?

Nothing like a little C4 to solve this problem or you could use C4's ugly sister SEMTEX. Ah! there's nothing like the smell of demolition in the morning!

@GeoN0JRJ I'm not sure - I've never tried to patch a broken base before. Maybe some filler like Plas-T-Pair ?

[GeoN0JRJ]

@bandersentv Excellent idea on lengthening the leads.

@joernone I added it to my watch list! Thanks!
