Thanks for sharing that - it certainly sheds some light on how skills-dependent making NOS boutique tubes/valves is. Hooray for technological advances in mass-manufacturing of them, otherwise we'd all be waiting a long, long time to keep our amps purring and roaring.
Wow, that was amazing. I wonder why he went to so much trouble to make them. He must not have any Guitar Centers near his house so he has to make his own. Anyway, I'm glad I saw the video. I have the exact same equipment in my basement and the kids and I are going to try to make some tubes tonight (just for fun)!
