I got this tube tester a few years ago and have used it regularly as my
first-pass tester for screening large batches of used tubes. It's a Hickok
Cardmatic wannabe, using punched cards to set up all connections. The on-panel
sockets are octal and 7- and 9-pin miniature; if you can find the rare
adapters, it will test tubes with 4, 5, 6, or 7 pins. (For more info on this
model, see http://www.tone-lizard.com/Tube_Test...ml#advertising.)

It has given me no operational or mechanical problems at all. I have done no
repairs, updates, or mods. Cosmetically it's a good 8 out of 10: the outside of
the wood case is scuffed and the front panel is a little dull in a couple of
places but there are no dents or scratches. Over 300 cards. No punch or master
card. I'll include a clean copy of the manual. High-res pix available.

$200 plus shipping. Pickup can be arranged, or I will meet the buyer up to 50
miles from Washington, D.C.
