You are bidding for ONE pair slightly used Sylvania 6SN7W B65 Metal Base Black Plates Chrome Top NOS Tested Matched carefully tested on my TV-7 as shown in the photos and sound wonderful in my hifi system. On my TV-7D/U, min good is 50 (65%) and max is 78-80 (100%). They are all tested over 90. These tubes were made for the US Navy so they are more durable than any other versions. Thanks

P/S: It is important to bear in mind that the shipping service I offer in the listing is $68.75 to all regions taking 3-7 days by DHL or UPS express to all regions world-wide. These ones are valuable so first class shipping is prioritized. Thanks a million
