Does anyone have any tube data for a Hickok Model KS-15560-L1 tube tester made by Western Electric? Thanks for any help.

I have one of these with all the paperwork & it works fine. This is really a model 539 rebadged.
Look at http://www.gdi.net/~padgett/hickok.htm for more info & links.

Ron,

I was told by Alan Douglas who wrote a book on tube tetsers that the Hickok KS-15560-L1 is similar to Hickok 539, but the tube data is not interchangable. The Hickok KS-15560-L1 has a filtered DC grid-bias supply, independent of the screen supply. If possible I would like to get a copy of your tube data. Thanks. Ross
