You are looking at a Bias Tool hands-free plate voltage tester.

One of these devices, along with your Bias Tool, will make your amp biasing job much easier and safer.
This device is the version used with the larger 8-pin octal based output tubes such as: 5881, 6550, 7027, 7581, 8417, 6V6, 6L6, 6CA7, EL34, KT66, KT77, KT88, KT90, and many more.
This device is *not* compatible with the smaller 9-pin mini tubes such as EL84, 6BQ5 and 7189- see our other listings for devices compatible with those tubes and amplifiers.
