In this business, people want to sound like they know something. So this happens a couple ways in an effort to impress.The more people can add to a name, in a effort to sound educated,the better the tube must be. Especially if the tube is rare (due to age, low production, whatever) and expensive.
I speak the truth when I talk to people. Eaxmple is the Mullard 10M 12AX7, or maybe EL-34. I have both in stock. If a guy asks me if they are worth it, I will not bullshit him in an effort to squeeze him for more money. I tell him to buy them because he wants them. Don't expect too much. The price is based on being collectible and rare. Nothing more.
Examples? Let's look at the most famous.
Sylvania 6SN7W Metal Base- I have had a number of these. Most are marginal for noise. Only one EVER was half way low in microphony. They test worse than any 6SN7GT I have seen.
Early Mullard 12AT7 - The early folded plate type. It is not a matter of if they are noisy...but when. I have had the heartbreak of buying a qty of Bugle Boys (the same tube was made in England, France, and Holland) and having them all suck. The later CV4024 trounces them in every way, shape, and form. For much cheaper. And last. I recently had a chnace to buy a stash of early ones labeled Valvo. They were fresh and perfect...and the price is right because there was a nice whack. My heart went pitter patter. But I passed because they SUCKED. Someone else is selling them though. For good bucks because they are "older".
Amperex Pinched Waist 6922 - Nothing tests as bad as these. A guy writes a tube lore using them as a buffer...where they don't have a tough life...and they take off. Right before all this stuff started I had found 100 pieces in perfect boxes. Out of there....maybe 10 were SOMEWHAT low in microphony. 50 were so bad they howled. I sent them back. I could have sold them for big $$$$. Dumb move.
Are early ones better? In some cases maybe so. I like the earliest Telefunken 12AX7, with ribbed plate...but the "experts" are so friggin mis-informed they will tell you the early ones are smooth plates in published reports. Makes you wonder, doesn't it?
There are no tru-isms. No blanket statements. Every type from any company must be evaluated, and then you have to ask if they work well in YOUR preamp.
I will come up with a fake screen name and started talking up the ultra rare "Triple Ripple Butt Plug RCA 5751 with fractured mica"
Repeat it three times. Then before you know it someone will ask me for it.
