Amperex 211

[LPD]

I picked up this pair of Amperex 211 brass based tubes. Can check for filaments but not sure how to test as my Avo tester doesn’t test a 211. Any ideas how to test these? I see they are quite desirable with the SET crowd

Check for filament continuity at the pins, otherwise you're going to need a bigger tester...

You probably need to send them to someone with a curve tracer. That's how David Berning tested 845s for a friend of mine back east.
