If you have a multimeter/VOM, you can at least check the filament on each tube for continuity. Even the most basic (read cheapest) meter will do for this check.

You can get the data sheet for each tube here: http://www.scottbecker.net/tube/index.html This will show you which pins to test.

Just pull each tube and see what the resistance is from filament pin to filament pin. I think that more than a couple ohms would indicate a problem. More than likely they'll just show open or infinity if the filament is bad.

Mind you, even with a good filament the tube may be garbage, but a tube with a bad heater filament is dead.
