Testing Model 20 tubes - Hickok 539A
03-28-2011, 05:56 PM
I dug out my old Hickok 539A tube tester to check tubes on the Philco model 20 that I am restoring. There were settings for 80 rectifier, but no settings on the chart for 27's, 24's, or 71A's. Does anyone happen to have these settings available for this tester?
Thanx.

When my pals were reading comic books I was down in the basement in my dad's workshop. Perusing his Sam's Photofoacts Vol 1-50 admiring the old set and trying to figure out what all those squiggly meant. Circa 1966 Now I think I've got! Terry

Thanks, Terry
Do you know if data from other models still match up to the 539A? The suppliment seemed to only contain addition to newer tubes. I did find "obsolete" data under the Model 752 and the setting titles seem to correspond. Thanks again Randy

Not sure. You could drop Steve a note and see what he has to say.
