Found an EMC Model 213 tube tester at a thrift shop this summer. It's a cute little portable unit in a fabric covered hard case, from about the early 60s. Useless without the chart (typeset on a literal typewriter) that tells you how to set the row of 12 switches & three knobs that dial in the proper test for each type of tube. Luckily I found a scan online!

Useless without the chart

And without a tube TV.

I've got plenty of vacuum tubes to test...if it still works. Who tests the tester?

Unfortunately, there's only one port to test with.
