[a_tubesupply]

Does anyone recognize this set? Zenith table / portable?
The only markings I can find are on the back cover: 610E26

I just got the set, and went through and tested the tubes... all seem to test ok...?
All I know how to do is test the tubes.
I have no sound, no video/ raster... but most of the tubes I see seem to light up.
Any ideas, circuit diagram???
Thanks,
