ECC801S / 12AT7
Telefunken vacuum tubes

Best quality double triode 9 pin audio amplifier tubes, garanteed 10,00 hours (mil. spec.). These fine miniature glass amplifier tubes have gray plates, thick mica spacers, and top round getters. They do not have diamond bottom, but we believe the manufacture may have been subcontracted to General Electric or others in USA in the 1970' or 1980's. They are printed in white with Telefunken logo ECC801S with various 5 digit codes. Boxes are standard Telefunken blue, white and orange printed ECC801S.
