the 5Y3 and 5U4 tubes. Both have the same pin out with the 5U4 rated for higher current. I have two plates and a single filament. I can yank the tube measure filament resistance and continuity test either filament pin to the plate pins in a min using a VOM
Explain more about how you can test TUBES using a VOM or DVM?
testing the filter cap with a VOM
How do you test filter caps with a VOM or DVM?
Use a 20,000 Ohm / Volt VOM To test Tubes? why a 20K ohm Volt meter?
