This portable tube tester was designed by the Hickok for the U.S. Army. It is rugged and highly portable. Hickok tube testers have the reputation of being the best ones ever made. They are highly superior to the "emission" type tube testers; test results are much more reliable (ie. if the tester says the tube is bad, its bad. If the tester says the tube is good, its good.) Virtually all Hickok testers are of the mutual transconductance type, so you really can't go wrong with one.

Some of the key features of this tester are:

Measures mutual transconductance which is the most reliable method of testing tubes known.
Tests 4 pin, 5 pin, 6 pin, 7 pin, Locktol, Octal, Acorn and 7 pin minature tube (Requires adaptor for more modern 9 pin minature tubes NOT AVAILABLE)
Tests most antique type tubes such as 45, 50, 2A3, 6B4G, 01A, 99, 6L6 etc. Also tests many Western Electric types such as 274A/B, 300A/B, 350A/B. (This tester is most well suited for testing older types. There is no data available for newer types such as 6CA7, 6550, 7027A, etc. If you need to test these types, don't buy this tester
Read transconductance directly or use "Good ? Bad" scale
Tests for shorts and noise
Includes copy of instruction manual and test data
