Substitutes for 7B7 tube

I am new to antique radio repairs. I was look on Nostalgia in regards to tube substitutions for a 7B7 tube for a Silvertone 7054. I see that a 7T7 tube will work, but I see on some other radio/tube sites that they will not work. If the 7T7 will not work what would be a good sub or replacement. Thanks any help would be appreciated.

Here may be a little more info for your cook book. I see it shows a few more substitutions. http://www.nj7p.org/Tube.php

Thanks. This will help.

As long as you are talking parallel heater a 7A7 will work, but since your 7054 is series string, a 14A7 will work...

In a series string the current(150ma) must match exactly, in parallel it the voltage that's most important...
