That tube tester is an awesome piece. Way more than you will ever need to test guitar tubes.
Nice 539,edgar.I had one years ago that was stolen from a studio I was working for.The microphonic test is a nice feature,but even tubes that show acceptable on the tester will sometimes be unacceptable in a high gain circuit like a Mesa.Just like a tube that is fine in a Fender lower gain circuit,can squeal like a pig in a higher gain amp.That is why the best test is "in circuit".I do get a lot of use out of my tester since I buy a lot of NOS tubes from "non-dealer" sources,so it is a big help in culling the bad ones.But for the average amp user,it is probably an unnecessary expense.
