Re: Testing 807's.
I found when testing the 807s for the amp I built, pictured, I came across several that gave unstable anode current readings in the valve tester but settled down and worked fine in use. The ones I used were bought from Russia. Out of 100, I only had one genuinely faulty one. Lucky, I guess!
