Here is a comment about this CDrom from a customer who purchased one: Hi, I received the Hickok 752/A CD-Rom today and I wanted to let you know that I am very happy with the material. Specifically: 1) The quality of the scans is much better than most (if not all) similar material I have found on the web.Many of the latter are unreadable. 2) The supplementary tube data sheets (foreign and obsolete) are of better quality and contain much more material than I could find on the web. 3) I could never find a specific calibration procedure for the 752/A. I do not know where you obtained it, but it is much appreciated. Regards, Shaun M No tube tester or tubes are included in this auction.
