And in contrast to "true" 1578's, check out these. These are standard Melz 6N8S's. Note the plastic top mica supports, oval mica shape, and solid plates. These are good sounding tubes....not nearly as good as a 1578, but still nice tubes. More on par with a Foton -- different sound presentation, but roughly the same "caliber" if you will. I'm rolling HARD on the floor laughing at the price on this one though -- this version can easily be found for $25 - $35 each, maybe $50 as a real stretch.

Do you have headphones with impedance of 50 ohms or higher? @sam6550a

All of my cans are 38 ohms or less.

LOL! He should change his seller name to "Bratva" to keep some distinction between BangyBang, Menifee, and this new fake storefront.

Thank you Gents for your information. Everything felt right that they were the real deal, but it’s reassuring to get confirmation. I am aware of the need to the possibility of having to re-solder the pins, and I do have someone in mind who could possibly do it for me if they need doing. All the same though, thanks for your offer Paladin79.

Ok I may throw some Sennheiser’s in the box, 38 might work but best to let you hear higher impedance just in case

To my more knowledgeable friends. I received these today. Melz 1578 ‘63. The cartons looked original and each tube was wrapped in the enclosed waxed information sheet. There has been discussions here regarding what is a real 1578, and what is masquerading as real.
So, have I bought “From Russia With Love” or “Colonel Rosa Klebb”.

Congrats! True Blue! REal Deal Holyfeild, Da Genuine Specimen.. . Ayatollah of Rock 'n' Rolla

They look OK, if not that ugly ink stamp. These seem to be with the black plates, not grey ones. I do not remember which ones are older or sound better (I do not want to discuss their sonic character as that annoys some of us). Any way, hereby these different types; shiny [grey] on the left, matt [black] on the right, you seem to have the matt ones.

None of mine had the ink stamp, I believe that is added on by some sellers, the purple one at the bottom that is. Mine were all the shiny black metal as I recall, I just have a couple left.

Drat I must have forgotten to include those, I think you got mystery tubes instead. Oh and a Marconi Bill would love to own.

I have the... chosen Marconi... (in all seriousness ... didn't sound bad at all) might have to give that one another spin to see if I still feel the same about it

OK, re-checked the record. The Russians say the best sounding Moscow-made 6H8C are with shiny perforated anodes, made from carbonised nickel: Moscow factory (МЭЛЗ), metal base, late Fifties. 1578 is an after-manufacturing testing quality assurance stamp, to certify less than 1% difference of transconductance between the triodes, and some other characteristics. These were intented for control panels of the nuclear plants, and the earliest Soviet "computer". 1578 quality stamp was awarded to tubes of different factories and different structures, according to my information. My MELZ tubes have neither ink stamps on the base nor 1578 etching on glass, just factory stamp and date etched on glass. I have seen large quantities of these tubes with ink stamp on metal base with the date as late as October 1979, which is funny, as according to my records MELZ switched 6H8C from metal base to black carbolite base in the 1960ties.

I love how you put computer in quotes.
I'm gonna have to get me one of these, just for that fact they probably glow pretty.

The solid plate Melz from 1956, and 1958 are identical except no perforation. I do have a 56 perforated but I still like the solid plate a bit better. The 63 (perforated) was the oldest I could find in quantity, I own other perforated plates from the late sixties, seventies, and eighties. I even bought a solid plate that had a purple stamp on it but no Melz logo lol, it has the matt grey plates. Several here heard that solid plate 58 but they are an aberration, the factory probably ran out of perforated plates or these plates never had the holes stamped in them. Jedi, Ripper, and Cowen as well as FLTWS have heard the solid plate version but they were comparing it to the 63. Personally I like the 58 better than any perforated plates I have heard but as always, YMMV. I bought them for far less than the price of $100 or more the perforated plates fetch. I do like to get others involved so I am not just posting my likes and dislikes. My local group has heard the solid plate and gave it one of the top ratings of any tube in our possession, and we have a serious amount of 6sn7 equivalents.
