kt88's for Quicksilver 90 watt silver monos

I have 1 mono with original kt88 (says China only)... need pair for other mono. Have some hearing loss in 1 ear... thoughts on tubes for hearing loss amp (left). Just get kt88 pair from Mike Sanders at Quicksilver or look into other kt88's.
I am unsure what your hearing loss brings to the question. I am not sure which KT-88 Mike Sanders is using as stock these days, but assuming your hearing can distinguish good vs better sound I prefer the Gold Lion Russian KT-88s. If undistorted higher volumes is your concerned, then you may be able to use the Tung Sol Russian KT-120s.
I recently retubed my Silver 90s with JJ KT88s from Mike Sanders. Mike knows what works best in his amplifiers.
