Any way to check tubes with a multimeter?

    Just to see if they're shorted? I have 6 Mesa STR420s. 4 of them came out of my Dual Rec. One of them is bad, though I didn't know it until I took the amp apart and found a burnt screen resistor.

    I was thinking about trying them in my amp again, but I have no clue which one is the bad one. I don't have access to a tube tester either. Any way I could check them?

    Not really with a multimeter. Check around for any antique radio shops, or ham radio fests in the area. There are usually guys around there with tube testers that will test them for free.

    A multimeter can only test for filament continuity - however, if the tube is lighting up in the amp, than the continuity is good anyhow.

    What part of Ohio are you in? There are a few antique radio clubs in Ohio and some if there members will have tube testers
