Dyna Jet Tube Tester Model 606 B&K Manufacturing Company Untested

Description

Dyna Jet Tube Tester Model 606 B&K Manufacturing Company Untested. This is a great estate find. I dont have any tubes to test it but the light came on and the needle moves a little when i pushed the grid emission  button as seen in the photos. Some of the books like the instruction manual look like they have got wet at some point. Please look at photos . If you have any questions feel free to ask. Case measures 11"× 8 1/2"× 4 1/4"
