    • Well, Google's 'advertising optimization' has now become so distracting as to trick people into visiting other sites. So I have removed advertising until I can find a better solution. One option may be sponsorship, anyone interested?
  • Sponsorship!
    • We are very graitful to Neill, who supports BAMA in gratitute with his financial support
      • It's free to use, but every little amount helps keep it that way!

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.
