Mullard GZ32 R71 Vintage 1959 Vacuum Rectifier Tube Bottom D Getter Shield Logo - $125 - (Sparks, NV)
Mullard GZ32 R71 Vintage 1959 Vacuum Rectifier Tube Bottom D Getter Shield Logo As you can see in the photos, we're including a new box that will be labeled with the manufacturer and type. We'll also use cotton to lightly pad the tube, which will reduce the risk of damage in transit. The Amplitrex AT-1000 tests rectifier tubes differently than most other testers. There is no "minimum". Rather, it measures the forward voltage drop and the reverse voltage drop. If you are unfamiliar with these important terms, you may want to do some research as it will give you a whole new perspective on tubes! We can assure you that the tube(s) being sold here are well within factory specification, and will perform beautifully in your system!
