All,
Tested the tube on my tube tester and am sure i tested it wrong and burned it out. Radio used to play, reinserted tube, no stations. Removed antenna and tested pin 8 with VTVM, reading 89 Vdc. Heater is ok. nothing on pin 3,4,5.
Comments?

For a start use your ohmmeter and check for shorts between the elements.
I have a big sign taped inside the top of my tube tester. It reminds me to check all settings before inserting the tube.

You can try a 12SK7 for a sub for now. See if your radio still works.

12SK7 did not make any changes.
I will wait for the new tube and post.
