This is a very nice comb-bound reprint of the instruction manual for the Hickok 533A tube tester AND MUCH MORE. I got the original from a retired Army Signal Corps officer. He spent the last 40 years compiling this information.

Don't be fooled. The one being offered for $4.95 is only 7 pages. This one is 122 pages!

This is a very nice comb-bound laser reprint of the complete manual for the Hickok/Western Electric KS-15750-L1 Tube Tester. Hickok also sold this same tester to everyone other than Western Electric as model 1575. This manual costs more than some of my other tube tester manuals because it is about 100 pages.

I don't know about you, but I would much rather use a real printed book than a CD. This manual is 51 years old and still quite usable. Will a CD still be readable in even ten years?

You are looking at a manual and a tube test condition book for the Hickok Cardmatic Tube Tester: -Original Vintage Hickok Cardmatic Model 1234B Instruction Service Manual from 1963. Code number 2490-471. In good condition.
