This is the BAMA archive. These manuals are available for download and free of charge. Do not be tricked into paying for a manual that is available here for free.
I am now accepting new manuals for inclusion in this archive. Contact and submission information below
Donation request: We have so many large format manuals to scan. It would only be possible with a large scale scanner. Such as a DS-70000 or something else that could scan 11.5x100 paper. See email information below (be sure to include BAMA in the subject line).
Few additional manuals added today.
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.
