Yeah, he probably has a nice tube tester or 3 laying around.
But good tube testers are easy to calibrate. Just follow the instructions to make sure the electrical tolerances are accurate.
Tube testers ALSO go for big money these days. There are one or two models, like the HICKOK 539C TUBE TESTERs that go for $1200-$2500 depending on condition. Although these Hickoks are great testers, the high price is due to the hype on audio forums, so this particular model will max your flipping profits. Or I’d be glad to take on off your hands :)
And congrats, BTW, the situation you have come across .... the rest of us can only dream of such a gift!
