[Milsurplus] Tube tester value

[J Forster]

A Triplett 3444 tube tester closed on eBay this afternoon (160142352442)
for $675, but the reserve was not met. Does anyone know what the A
version is worth on the open market? The A version tests a much wider
variety of tubes, including things like 955, 956, ... .

Note that this is just curiosity. I'm NOT either interested in buying
one or selling mine.

Thanks,
-John
