I hope it is a simple thing I am very excited to have one even though I a new tube convert. Got lots of tubes from him to test also. Any help is gladly appreciated.
The Anko tube checker was made in Milwaukee, by the same firm the made the U-test-um drugstore tube testers.
I don't remember how to set it up, but it was simpler than the Eico's and Heathkits of the day.
Also, regarding the load it placed on the tube being tested, it put a real load on the tube. You had to let the tube warm up completely or it could be damaged. You would see the tube sparking inside.
I haven't seen one or used one in 40 years. There must be calibration pots inside to compensate for the initial setting.
