Hickok tube tester page

[Rick Robinson]

Fellow Hickok owners,

This is THE page for Hickok tube tester owners.  Padgett maintains the best
collection of Hickok info on the web.  What he doesn't have on his page he
posts a link to.

I've used his 600A calibration FAQ and found out my old Hickok is still
right on the money without any needed work.

73,
