Oh believe me, they are ALL DEAD!!

Found an equivalent tube in my supply and did a comparison and you can see a glow.

ALL tubes are shorted with NO glow no matter the heater setting... Wonder how much voltage they shoved down the 1.5v line? they didnt mess with the 90v side...

And oops, my bad,, just an AM model, the dial scale threw me...

Thanks for the links folks...

I have absolutely no doubts about your findings. I've seen it many times before!
The dial scale is probably calibrated in wavelength, as well.
Many radios, of that era, used the wavelength scale and were mistaken, to be multi-band. Kilocycles, meters.

Did not mean to imply the tubes were not bad or question your findings. Just wanted to pass along to others that may read the thread later on that it is not easy to visually tell on GT version of these tubes if they are in fact lite up.
