In the Cave for a Vinyl Therapy Session. I just popped a couple newly acquired Sylvania Gold Brand Triple Mica gold pin 5751's into the ZP3. These are NOS so a little burn in will be needed but they sound fantastic so far. I'll go get Joe's Tube Lore from 1999 to refresh my memory what he said of them. I have and like all the Sylvania triple Mica 5751's, these gold pin gray plate as well as steel pin gray and black plates...both Mil spec and Sylvania branded. They are all great.
Started with a bit of Frank...side one then on to Art...
This ebay Art Pepper MSFL ebay purchase played for the first time today is very clean...nice...
"Sylvania Gold Brand grey pl ate gold pin - OK, this is the legend. When people talk wantonly about the famous Sylvania Gold Brand 5751 gold pins this is the tube they are referring to. Its strength is its midrange, but it may also be its weakness. The mids here are full, lush, tangible and maybe (just maybe) a trifle overblown. Occasionally i find the lush full vocals obscure just a bit of detail and reduce transparency slightly, but the mids are so lush I could understand how you might not care. The tube also has a measure of life and vibrancy, similar to the Sylvania's black plates and it also has a bit of the forwardness that's seems to be endemic to Sylvanias in the 5751 family. I've lived with this tube enough to know I could use it quite happily, though that would be in the context of a fairly neutral system where its own colorations would not go over the top. If your rig is already warm, smooth, lush and a bit lacking in detail this guy could turn things just a touch syrupy. But given the sound of a lot of cd based systems he could be just the ticket... Availability on this guy is limited. His reputation has made him a rare, if not outrageously expensive beast."
