Description

2 Chatham and 2 Tungsol vintage 6528 Military Spec Twin Triode High Current Power tubes, USA, untested. The 2nd picture shows the top of the Chatham tubes, the 3rd picture shows the top of the Tungsol tubes. Once of the Tungsol tubes has a broken guide pin, which with care in aligning it in the tube socket, has no affect on function or performance. These are impressive very heavy, well built and well designed tubes, 3 mica design, black plates, D Getters. My tester does not test these tubes so they are untested. They have excellent potential and are known for their excellent sound and performance. The shipping cost includes safe packing, insurance, prompt shipping and tracking number. Buy with confidence, see my feedback. Good listening, SonnY :) SOLD AS IS
