Here is a fantastic PAIR of GEC KT88 power tubes!! These are vintage U.K. made originals- NOT current production Russian copies!! Triple O getters. On our military TV-7 tester, with 44 being the baseline for good (65%) these measure 72 and 71 -a bit over 100%. No shorts or gas. The getter flash is very strong- with no signs of thermal stress!! These will be VERY securely packed for shipment anywhere (there are shipping exceptions). Shipping cost in USA via USPS Priority Mail with signature confirmation (required) will be $12.00. Outside the USA we will only ship via USPS Priority Mail International because of value. We have shipped hundreds of tubes worldwide and know how to pack so they will not arrive damaged.
