“So far, so good. Bought these to solve a fuse-blowing problem with my Caryt SLI-80 HI amplifier.”

“Tube replacement for BAT VK-P10. Unit is 12 yrs old on original tubes. Started experiencing left channel loss of amplitude with distortion. Upscale recommended the Electro-Harmonix for BAT gear. I replaced all 8 of the 6922's and both 6SN7's with the same Electro-Harmonix Platinum grade. Problem fixed. Spinning vinyl of course, but it will be a while before they are broken in.”

“I’m very happy with this tube. Super low noise and microphonics is welcome in my home. The soundstage has nice dimension. This is a fantastic value for my single tube Schiit Saga preamp.”
