Hi all, nice site!
I just bought a great little tube radio and it works good too! The thing is there are two tubes inside with connectors on top that seem loose. There is a wire attached and it's pretty snug. I'm concerned because the little cap on top is loose. You can rotate it back and forth a little bit. The tubes work, or at least the radio does, but I think it is odd that these caps are loose. Is that normal? Do I need new tubes?

Thanks in advance,


John White

Hi John,

What you are describing is actually pretty common. The cap is a connection to the anode and if the tube still works, then there is no problem. A wire passes through the glass to that cap, and as long as the tube isn't cracked or the wire broken, the anode cap being loose is more of an annoyance than anything else. A little drop of super glue run down under the cap will secure it, and you can scratch off any that is visible after it dries so the tube looks good as new.
