Ten syl-gb & h.p. 5963 comp.rated audio duotriodes
Here are Ten 5963 Computer Rated 12AU7 Audio Duotriodes. Six are Sylvania & Five of these are Sylvania Gold-Brand. Four are H.P.. All Ten have grey plates with halo getters. All were tested on a B&K 747B DMC tester with the following results. The Sylvania Gold Brand tested 111/109, 99/105, 100/104, 96/98, & 94/93. The other Sylvania tested 95/97. The H.P. tested 95/91, 98/98, 100/101, & 98/100. So all tested like new with no shorts or grid leaks. The Gold Brand the print has faded, but is still all there. Some bases are dark from age.
