12LP4 PROBLEM
3/2/2009 11:52:22 AMDave F
Hello everyone, while removing the 12LP$ CRT from the chassis of my Admiral set, the back bakelite end came off, revealing the wires that go to the socket. Does anyone have a suggestion on an easy way to get these wires to go back into the socket so that I can get this tube back together? I have tried many times, and can't seem to get them all to go all the way into the socket.
Any help is appreciated!

Use a solder sucker to remove all the solder from the base pins. Then solder thin extention wires to the crt leads. Feed the wires through the pins, and pull them all into place. Heat each wire to release the extention while soldering the crt leads to the pins. Use epoxy or super glue to hold the base on the crt. This takes a little time, but it can be done.

Thanks for the answer, what is a solder sucker, never used one, are they readily available>?

A glorified turkey baster. Google "solder sucker" for more info and sources. RadioShack used to sell them.

Might also try using desoldering wick or braid?

If you go the poor man's route for this (like I do) simply heat the pin up and then run an appropriate sized drill bit thru to remove the solder while the solder is still soft.

:Another thing I have done is to heat up the socket pin, one by one, and qwhile it is hot, bang it on a piece of wood . This forces the solder out and you should see a nice hole where the solder was.

Hi Dave,
It seems you may have been suspecting the picture tube anyway. If so you may be interstd in http://www.hawkeyepicturetube.com/

They rebuild picture tubes. I haven't used them, but they are the only one I know.

Best Regards,

Thanks everyone for the info. I am going to try and remove the solder, and put new wire into the socket, and then attach to the leads coming out of the tube, then glue it. When I just slide the wires into the openings on the base, which is no easy task, I might add, they dont make contact somewhere, because the tube filament doesnt light up. The frustrating thing about this is that this is a NOS 12LP$ that worked like NEW, and now I have to use the old dark tube with a brightener until I get this fixed.

Unless the leads have broken off right at the glass, you should be able to salvage it. Did you solder on lead extensions and then re-solder the pins? Before putting that socket on, you should be able to identify the filament leads and do a resistance check to confirm the filament is good.
