no longer for sale

A superb, never used matching pair of RCA Red Base 5691/6SL7, boxed by Motorola and labeled for Westinghouse. These had never been in a socket before I put them in my tester. Test identically at 1900/2000 & 1900/2000 on a calibrated Hickok 539C tester where minimum is 1100. Listening tested, excellent sound. Great for Almarro, Eddie Current, Cayin, Cary amps and preamps, etc.. $160 firm plus $5 ship in US. Thanks.
