MILITARY TV-7D/U
tube testers 2014
A French made tube tester for both American and European tubes since 1950.Voltage selector 110-245v 50Hz. Dimensions H450 - 340 - D165.
Weight 7Kg
It was made in Canada by Stark Electronics Instruments.The TV-7 series are built like tanks and seems to me, to be one of the best designed tube testers ever made. They are based on a Hickok design and are great for testing real old tubes prior to WWII. It will test many, but not all, tubes made after WWII.
