Hickok model 6000A vintage tube tester / one-owner

The Hickok 6000 and 6000A tube testers are an updated version of the famous Hickok 600A. The main differences are the addition of a transistor tester and the way the sockets are mounted. In the 600, the sockets are indivudially mounted to the panel where the 6000 has all of the sockets mounted on a "plate" or "island" which plugs into one 11 or 12 pin socket on the front panel. The idea was that if a socket went bad, you needed only to purchase another socket plate and plug it into the tester instead of replacing one socket and soldering all of the wires. Now that none of the plates are available, you have to replace indivudial sockets one both testers. The difference between the 6000 and 6000A is that the 6000A has a socket plate which has all of the modern sockets (octal, 7 & 9 pin minature, nuvistor, 9 & 12 pin compactron) and the 6000 has the older socket plate (4, 5, 6, 7, octal, loctal, 7 & 9 pin minature). Therefore, you would not want a 6000A if you intend to test mainly older tubes (45, 2A3, 76, etc.).
Measures mutual transconductance which is the best type of tube quality test.
Has good-?-bad scale or will measure transconductance directly in micromhos
Will test for gas, and shorts between all elements
Built in roll chart with settings for all common tubes.
Includes obsolete tube and foreign tube supplement from the factory
6000A has 7 & 9 pin minature, octal, 9 &12 pin compactron and nuvistor sockets
This tester comes complete with a scroll type tube chart from which the technician can find guides to testing individual tubes from 0Z4 to 8628. In addition, the supplemental test booklet covers tube data for many obsolete tubes (0A4 through 9006), and foreign tubes as well (1AJ4 through 3800. Also featured is the removable lid via offset hinge pins; simply slide the lid to your right, and lift it off and out of the way.
