Amperex Orange Globe (Siemens ?) EL34 Tube – Used – Amplitrex 76% Gm

Specifications

Up for sale, a vintage Orange Globe logo Amperex EL34. I'm guessing this is late 60's manufacture since that's the heyday of the orange globe tubes. I'm not an EL34 expert but believe this to be a Siemens made tube. See pics. Test results are included in the images. Sorry, no box. This will ship wrapped in bubble wrap. My test rig is shown below for reference. I feed the tester with 116.4V sine power (my wall voltage is all over the map, frequently approaching 130V in the summer months). This allows for absolute consistency with testing and/or matching. All tests are run in Fixed Bias mode which produces the most conservative numbers. US bidders/buyers only please. This will ship tracked and insured.
