I'm aware of the computerized unit at
http://www.tubesontheweb.com/index.htm, but it's out of my range. Is there
any way to find out what the fixture looks like, better yet a pix?. Now I'm
wondering if an old IBM keypunch card maker could be the base. I can't
recall the model number., but there was no shortage.of them 40 years ago but
I'll bet you could find one cheap if you looked hard enough.

I have never seen the punching fixture, but think it consists of a
number of punches with a plate and die that matches the plates in the
tester. Punches are added or removed, depending upon whether a hole
is to be punched in a certain location. When all punches are in place
the (guessing) lever is pulled and a cam drives the punches through
the card into the die. Even this method is pretty darn slow. You
would be working for a long time to make up a set of thousands of
cards. Now there was a guy selling some cards on Ebay a year or so
back--he was in California. I don't know if he has any cards left.
