I finished restoring a 116 b and boy does it sound great but the shadowmeter is giving me fits.
I did the realignment but the meter will not work. The meter ohmed out at 813 ohms and the voltage swings from 0.78 volts dc tuned to .221 vdc untuned. I checked the 77 and 78 tubes and even changed them out for new ones without any change.
? What voltage should I expect to see on the shadow meter and what current should I see?
