Description

This Hickok 580A Laboratory Grade Tube Tester and Analyzer, with Three Transformers for Filament, Plate, & Screen, Plus 300 VDC Available, is in Excellent Condition.

I used a Test subject (6CL6) to test this unit and it appeared to work as it should.

It is being sold as is as described for the family of a silent key

This rather rare Hickok tester, is considered to be their BEST EVER tester and "lab grade analyzer". It was made in 1965.  It is full featured tester and analyzer. It is considered far above the 539C for many reasons. In some ways it is a cross between a Triplett 3444 and an AVO TCM 163.

The only three transformer tester Hickok made, filament, plate, screen, plus the only true transistorized one as well. It is able to stay stable better than any Hickok. It weighs a lot, 30 pounds, so keep that in mind. It is smaller than other Hickok, at 19x15x7 inches, It will not need service for perhaps 30 years or more.

The gm meter is a high accuracy type able to measure from zero to 60,000gm in selectable ranges.  Multiple ranges for rectifiers as well.

Inter-element leakage testing not simple short testing, to 50 million ohms. 

The built in milliamp meter for matching tubes, has been extended to not just 50 ma but a choice of 50ma or 100ma (1x or 2X) which enables it to measure much high power tubes such as Kt88/6550, etc.

Hickok testers, Even the 539C, are limited to unfiltered 150vdc for the plate and screen, which drops a lot for a power tube, to 130vdc or less.  The 580A has selectable FILTERED D.C. voltages from 6.3vdc to 300vdc for both the plate and screen independently, plus the bias, something very few testers offer.
The bias dial is for an an approximate value, the main meter actually reads the bias as a true value and is use to verify that. Range is 0 to -50vdc.
The deck has jacks for the plate, screen, and grid for those tubes which have top caps, or you can monitor those voltages with a DMM if you wish ( must be removed during the "leakage test" or a false read will show.). The tube sockets cover from 4 pin thru Acorns and compactrons.

The gas test or grid leakage test is extremely sensitive. It can detect as low as 50 milli-micro- amperes. There are 1,000 micorampheres in 1 milliamphere.

There is also a "LIFE TEST" to estimate the remaining life of the tube.

Dual element tubes tested with on button, that includes pre-amp (12xxx, 6dj8/6922/7308, 6sn7, etc., and diode tubes.
Filament: 0 to 117 vac. Also, if a tube is sensitive to filament imbalance, you can 'tune out' that interference, for a superior test  Very important for ultra sensitive tube positions such as moving coil amplifiers or triode power tubes.
Other Tubes which may not be on the roll chart are easy to figure what setting to use. Since each selector goes to a different socket pin, and voltages are also selectable,  you can customize the tester to you needs.
