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

Product Details Vacuum Tube, KT77, JJ Electronics, PowerT-KT77-JJSold individually The JJ Electronic KT77 is a reproduction of the original tubes that captures the sound that made the KT77 famous. In their typical fashion, JJ has built this tube in a solid construction that is robust and highly reliable. This tube has more headroom than a typical EL34. The low end is fat and defines with detailed and responsive mids and smooth highs. This is an excellent tube for adding more power to the sound of an EL34 amp. Not what you’re looking for?
