One NOS NIB GE JG 12AY7 vacuum tube. Made in the USA. White label, 12mm gray plates with top bent square getter. Codes: 5-09 and 188-5. Tested twice on a fully restored and recently calibrated B&K 606 tube tester. No grid emissions (gas) or shorts. Test results: 88/90. For reference, most NOS 12AY7 tubes test around 86 and the minimum "Good" on the B&K 606 is 65. The test results are written on a removable vinyl sticker that is attached to the box flap. The box is original to the tube and will be included. I also tested this tube for microphonics and performance in my '67 Bassman (in position V3). There were no microphonics present and it sounds great. This tube is in very good condition, with clean pins and moderate silkscreen wear. Please view the pictures for more details. Free shipping to the US via USPS First Class. For international shipping rates please use the shipping calculator. A tracking number will be provided upon shipment. If you have any questions feel free to contact me through eBay messaging. Thank you for looking and please view my feedback and other items.
