[sdiy] Saved just prior to hitting the dumpster

[J. Larry Hendry]

I am the lucky (?) recipient of a Knight-kit (of Allied Electronics) 400A
tube checker.  Looks like the original owner did a neat assembly job.  But,
I need to do some wire checking.  It does not appear to be 100% functional.
I was lucky enough to get all the docs too.

Anyone else have one of these puppies?  I know lots of you guys (like me)
are old enough to maybe having built some stuff with tubes before they were
hip. :)

Funny, there is no web site listed in the docs. :)
