Sorry if this has been brought up before.
Is there any way to test tubes without an emission tester or other type of tube tester? If not, are there any recommendations for a tube tester that would be functional in the $100 range?
I got 4 Fotons off of eBay that I think were dead to begin with, and want to know how to verify before I request a refund.
You can test them for shorts with a DVM, but no way I know of to test for emission or GM without a tube tester.
