Hickok I-177 Tube Tester
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
- Tester is in good working condition.
