This may be so, but be careful if your amplifier is prone to microphonics as most of the early 6SN7’s are more microphonic than the later versions. This is very dry humour. There will be more soon. Definitely softer, more rounded, duller. I have several Valvo’s and a few Mullard’s in stock at present.

In my Linestage, in my set-up, the Sylvania has the very best tone of them all. Rumor has it that the metal base versions are even better but that is stupid money The Mullards are wrongly marked as 6SG7.

Top 5 6SN7’s | Headphone Reviews and Discussion –

Rolling 6SN7s can get expensive, especially if you need a quad. They just dont have the depth or detail. These are shaped more like a standard 6SN7. Mar 31, at 2: Not as exciting as the Sylvanias, but also less tendency to sound etched. These are GREAT for really clear voice and have good detail a little better than bbest tubes abovesmooth and flowing good jazz style tubes but the clarity, the focus just isnt like the first three.

Legendary tube with the red base. I had a great deal of fun rolling them.

These were a military low noise tube made and screened by tung sol that have round plates, black glass, brown bases and are specially matched between the dual triode sections. I literally have hundreds of tubes, which I have to eat because, I couldn’t make 4 of a kind!
