6B7 adaptor to a more modern equivalent.
4/19/2010 11:00:58 PMDave Froehlich
Hello All,
I don't have a 6B7 for my radio. But I can probably make an adaptor. But What tube is most like a 6B7?

"Twin Diode - Remote Cutoff Pentode" That's a "7D" tube outline. 6.3 volt filament.

Thanks,

Dave

Hello Again All,
It's a 6B8 that could be adapted to a 6B7 socket. I might have one of those.

Thanks,

Dave

Norm,
Thanks very much for the tube. The old one had a very loose envelope. It turned out that the tube wasn't the problem after all. I took out the chassis and checked everything and the large power resistor was touching something it wasn't supposed to. I moved it out of the way and "like magic" the radio was working. I must have accidentally moved it when I was replacing the capacitors.

Thanks Again,

Dave

Good to hear you have the radio working. Now you have a spare 6B7. Might need it in the future.

If the glass envelope is loose at the base, you can dabble a small amount of super glue around the joint.

Doug,
I have tried all sorts of "Super Glue" and "crazy glue" and it has never worked for me. I don't find that it can hold anything together at all. It always falls apart. Plus, it has a very strong odor. I've tried that on tubes and it never holds. I have also tried tape and that doesn't work either. So I'm going to keep the tube as it is. I think that the original glue was much different. If I had that glue I think I could get it to work. But what kind of glue was it?

Thanks,

Dave

Dave, why not give JB Weld a try. I use it and holds for me. Also have used a glue gun but if tube gets very hot may not work
