Free shipping worldwide and it comes with a 14 day guarantee. It tests at 100/96% with no shorts, no grid leakage and no gas on my computerized Western Electric Hickok KS-15874-L1 tube tester that I calibrate weekly. Please check my other listings as I will be listing over 200 different tube listings this month. I buy ham radio, audio and tube estates/collections & hoards, please call me at 530-725-0777 if you have an estate, collection or hoard you are looking to sell. I also offer reasonably priced professional tube testing services on above mentioned tester. Thank you in advance from Nelsen KE7RDT
