8877/YU-158 Tube: This is an industrial grade 8877 tube for an Alpha 9500 and similar amps. The best (lowest grid current) tubes were pulled from the 8877 assembly line and rebranded YU-158 for the medical device market (and sold at a much higher price). This is an excellent tube tested in a 9500 and delivered full power out +. Comes with socket (which you can just pull off if you don’t need it).
