Hi Jim,
Yes on your set if one of the tubes filament is burned out (open) none of the others will lite up.So I've got a few questions for you. Can you read schematic? Do you know how to count the pins on your tubes? Do you have a volt/ohm meter? Schematic is here http://www.nostalgiaair.org/PagesByModel/683/M0013683.pdf

Ok, So to test the filament on the loctal tubes measure across pins 1 and 8 and the octals across pins 2 and 7. Should show a very low resistance if good.
