“After inserting this rectifier tube on my Icon Audio ST-40 MKiiim integrated amp the sound was different, but in a really good way? The bass was tighter and there was a bit more detail. So I asked the folks at Icon Audio if the rectifier tube can make a difference to the sound and they answered absolutely! I read really good things about the Gold lion U77 so I decided to get one from the folks at Upscale my go to store for tubes and gotta admit this is a wonderful buy along with the great service!”

“I was planning on going for an NOS Mullard or Amerex until the guy who repairs all my vintage gear said to save my money and go with a good Russian rectifier. Hard to really know without a side-by-side comparison, but I'm listening to it now on my Bogen DB230A amp and I am not missing a thing. A great buy. Thanks, Kevin!”
