Geez Louise, rodman. Roger not being incompetent is what is called a joke, apparently one too subtle for some. I don’t accept the word of the owner of the damaged Music Reference amp, but I do accept the word of Roger Modjeski, and what he has reported about what he discovered when he inspected the damaged amp, and what he has to say about the Hi-Fi Tuning Fuses he found installed in the amp.
I have provided no evidence, and therefore am not going to "provide FURTHER EVIDENCE". All the info on both that I have read, and have repeated here for the potential benefit of fellow tube power amp owners, has been that provided by @ramlabs. Perhaps Roger will once again provide that info for those truly, sincerely interested. I’m done trying to help fellow tube amp owners. Talk about looking a gift horse in the mouth ;-) . Good luck, ya’all!
