    • 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!

      • It's free to use, but every little amount helps keep it that way!

Tube data cards for the SECO model 107 tube tester.
Compliments of Ron Shaw. KC0DKI.

seco-107-troubleshooting-chart.jpg:
I ran across the page in my grandfathers seco 107 tube tester,
which years ago inspired me to start playing with tube 
electronics. I'd like to submit it in hopes that it may 
help others with the same tester.
