has anyone built this? I am unable to test it in a tube tester, I assume because of the diodes. I would like to be able to test it before I glue the glass dome down. I used the cx5676 tube.

I don't see anything that would make the assembly misbehave in a tube tester. What does it do?

why not just plug the adapter into the tube socket without the glass portion to test it.

Of course I tried it before I glued the glass one. Most testers use ac on the filaments which in this case along with the diodes is throwing the tester off. Maybe higher end testers has a DC feature for the filaments.

In the old ARF we had a lengthy discussion about the effect of breaking the vacuum of 01A tubes. I definitely destroyed 3 of them, when I did it - the silver liners were either getting milky or even flaked off the glass in an instant. I therefore resorted to a glowing SS tube a la Strelow http://www.greenhillsgf.com/Project_SS-Tubes.htm
