The big score from The Kutztown radio meet at Renningers! Well, actually I did not buy much due to me being broke - but I did get this.
This is a Birtcher model 70 Semiconductor Tester, apparently used by Sylvania on their transistor production QC line back in the 1960s. This thing does a bunch of tests on diodes and transistors, using curiously familiar plug in modules. It used an interesting mix of tube and semiconductor technology. Let's look at it.
