Well KT120's arc just like 6550's do. Possibly a bit less often. With regard to the Chinese 6550's of decades ago. Frankly they were awful tubes. But that was all that was available. They looked like the Tung Sol coke bottle 6550 but that's where the similarity ended. Their failure mode allowed the heater to work but not much else. The light was on but no one was home so to speak. I'm guessing in the D-125 more than one tube arced at the same time. The Chinese tubes liked to do that back then. The only Chinese tubes I will use even today are the EL-34 Treasures. That's it. Once bitten twice shy. Remember, at the time the Chinese were making the 6550, the Russians were still trying to gear up to make one. ARC helped the Russians make the 6550. I just wish they hadn't initially used the GE 6550 as their model. I always thought the Philips Sylvania 6550 was a much better tube. Initially the Russians were trying to change one of their stock beam pentodes into a 6550 but that failed miserably. The Russians never stopped making tubes. Remember, the Winged C 6550 was probably the 12 version of the Russian 6550. Trust me, I saw every single version of that tube over the years. Some good some not so good, and some without any getter flash at all. The KT-120 represents what is considered to be state of the art in Russia. The KT-120 looks to me to be a modified version of one of their radar tubes. It's a winner.
Audio Research VSi60 integrated reliability?
Just wondering the reliability of the VSi60 integrated. Am tempted by the idea of a tube integrated, but a little wary with the stereophile review and comment about exploding units. Saw a previous a'gon posting with quite a few replies about another similar situation which seems to have been deleted. Anyways I hear quite a lot of positive remarks about ARC's reputation and reliability, but those posts frankly are ridiculous if the amp is exploding.
