“After breaking in, bais is very stable. Tubes sound much better comparing to old stock tubes from ARC which is expected. But buying from upscale give me the peace of mind that I am getting top quality stuff for my Ref75SE.”

“The sound is proving to be impressive after a few dozen hours. I’ve docked a star because one of the 4 tubes I received is noticeably smaller in its egg-shaped glass (but the internal parts look the right size) than the others which gives an unbalanced appearance to the amp. Maybe I was given an older tube from a different production run.”

“What can I say? They are working as advertised meaning extended at both ends of the frequency. they are expensive because they are Russian? Wonder if they will ever be made locally.”

“I'm having issues getting these tubes to bias in my ARC Ref250se amps, can't adjust to bring the meters into the acceptable range. Any suggestions would be greatly appreciated.”
