I just got a neat old GE with a telegraph dial, (posted on another thread). However, the first thing I did was try to pull off a grid clip, effectively pulling off the cap too. I did not break the glass seal and I think this can be repaired. I don't want to try, though, with out some input. I seems I read somewhere that you can drill a small hole in the cap, carefully solder an extension to the wire coming out of the tube, and then solder the wire to the cap. Then you re-glue the cap to the tube. Does this sound do-able?

Hi Terry

Yes it's do-able. Use a soldering iron and melt solder from the grid cap. You should find a hole in the center. If the wire is long enough you can solder the grid cap back on your tube. I use epoxy to make a good mechanical connection.

If the wire is too short seperate a strand from hookup wire. Wrap and solder it to the existing wire. It can be soldered to the original grid cap.

Great! Thanks Norm- just what I wanted to hear. I'll post later if it works.

I agree with all. If th stub is long enough to allow you to place a heat sink (those little spring clips used to help you solder solid state components) between the glass and still leave you enough room to make a connection, why not use it, lest the heat threatens the metal to glass union on the tube. I would clean off the end, wrap a little piece of wire around what's left solder it, drill a small hole in the grid cap, epoxy it in, and after the expoxy cures (next day, quicky csolder the extention to the top of the grid cap. Good as new!
