That sort of thing is what made me leave the electronics "rat race" in 1992. The above simpler explanations have all helped to add to my store of "useful knowledge." But I still don't understand why a valve showing "clapped out" can work as well as one showing very good! In many way, having a valve tester has now muddied the water even more for me. My old "homebrew" valve tester gave me a much more realistic pitcure of the condition of valve, and I may well develop the circuit further!
