Just received a calibrated (Oct 1007) Hickok 6000A from Virginia Tube Audio. I know it's not like the Amplitrex or other fancier meters but it's really a cool toy for a hobbyist like me. I am having all kind of fun going over all the tubes I have and grading them. Now I will know for sure that a tube is live and well before I put it into service since I will throw out the bad ones. Hopefully, matched tubes (in mutual conductance) will stay matched in my system under real load. Here is to tube rolling!

If any of you want to test your tubes, it will cost you a beer.
