kb142
Info
Attached please find the instructions and tube setting charts for the Olson Electronics KB-142 tube tester. The first page is marked 3/62 in the lower left-hand corner. I’ve searched have been unable to find a scanned copy of it anywhere, so I scanned my (rather tattered) copy to share with others. I’ve also included a photo showing the controls referenced in the instructions. Sadly, they didn’t include a schematic diagram, nor is one to be found in the unit itself, but the KB-142 is a generic emission type tube tester and thus the circuit similar to other testers of this type.
