Is that some entrepreneurial spirit will likely take note, and begin manufacturing a quality tube tester again. Perhaps they already have, I haven't checked. With the number of tubes coming out of Russia and tubes and amps coming out of China, I'd be surprised if it hasn't alredy been considered.

A currently produced tube tester that is a better mousetrap, too! Ain't cheap, however...
I have about 14 pieces of equipment which use tubes. By my standards, that's not a lot.
If I were doing what Jim McShane or Mike Samra are doing, and needed a new tester, I could see making an investment in the Amplitrex unit.
Thanks for letting me know it exists!
decent repair service for old tube testers.
That said, as a former bench tech, I can't think of any piece of electronic equipment I would rather NOT have to work on, what with all of those wires and switch contacts to deal with.
I can only imagine the "bird's nest" in a complex tester.
I have a Knight 600A, which I picked up from a guy at work for $10, about twenty years ago. The Knight was sold as a kit, so it's fairly simple, both in construction and (limited) function.
I've thought about buying something better, but I only have a handful of tube amps, preamps, and tuners. After reading numerous comments on the DIY tube Asylum, I've followed the suggestion of testing tubes "in circuit", rather than spending high dollars on a good tester.
Well it is a mess of wires for all the socket connections, but circuit-wise the B&K 707 is not actually that complex (some of the switches are complex beasts)
Someone making a modern one would do well to create a [big] printed circuit board that need only sockets to be soldered in.
Never trust an Atom, they Make Up everything!
