FS: Hickok 752A tube tester

Archived from groups: rec.audio.pro (More info?)

I apologize if this is a duplicate posting--I put it up yesterday morning, or
thought I did, and never saw it appear.

This model probably doesn't need explaining in this group. It is toward the
upper end of the Hickok line--in fact, it was introduced to replace the 539C,
according to Hickok wiz Lewis Padgett.
(http://bellsouthpwp.net/p/a/padgett46/laterh.htm) It's a terrific tester. I'm
selling it only because I've acquired a KS-15784 L2, the Hickok-made Western
Electric version of the Cardmatic.

Condition is a very conservative Good ; I believe most would call it Very Good
or better. The case has the usual marks and dings. The panel has shiny wear
marks around a few of the dials but is otherwise extremely clean.

I've regularly used it for thorough tube checks, employing less-sophisticated
testers to do Go/No Go screening of batches of used tubes.

A convenient feature of the 752A is that it can check both sections of dual
triodes just by pushing a button--no change of settings is needed. Great if
you've got lots of 12AX7's to check! The roll chart works fine. There is a mild
"tick" at a certain point in the rotation of the Bias control, as if a turn of
the resistance element (it's a wirewound control) is sticking up just a bit.
It's never been a problem, but I have a spare pot I will include (these are
very hard to find because they were unique to Hickok). A pin on one of the
miniature tube sockets could use tightening, but again it's never been a
problem. I have full documentation, including settings for many obsolete tubes.

$400 plus shipping. Pickup can be arranged, or I will meet the buyer up to 50
miles from Washington, D.C.
