I found this on Ebay this morning. Right in my tube sweet spot with what it will test.
Power Tube Rule Tube Tester
Seller has great ratings, other testers for tubes and capacitor .
Thoughts? Concerns?
Thanks Alan
Well not expensive prices, seems it measure only parameters associated to emission, what not tremendous useful if one buy new tubes, unless one are a tube broker and will matching tubes for sale, its missing gas measurement capability, otherwise looks good by what I can see.
A cathode heather for getter activation capability are much more useful to me than a tube tester to prepare NOS tubes for use IMO.
