6SN7 / 5692 Tube ListThis is a long one folks. There seem to be a bazillion different types of 6SN7's. If you don't see what you are specifically looking for, please email me.
Audio People Please READ! There is no way I or anyone else can tell you how any given tube will sound in your equipment. There are too many subjective variables for me or anyone to tell you unless they have your equipment and your ears. You need to try different types to see what you like best. I know that I would sell more tubes and make more money if I did, but I'm not in the business of pedaling B.S.

| 5692 RCA Red Base New | RCA
brand-red base. The 5692 is a commercial "premium" version
of the type 6SN7 tube. This tube was first developed and produced
by RCA. They were part of the RCA "Premium Red" line which had
red colored bases. Any 5692 with a red base will have been
made by RCA regardless of the actual branding on the
tube. True 5692's have extra support rods between the top and
bottom mica spacers. This helps keep the plate structure rigid
which eliminates microphonics. They also have long life cathodes
rated at 10,000 hours of service. The high cost of these tubes is
justified by their long life and great sound. These are "NOS" RCA or brand name other than RCA but
manufactured by RCA |

| 6SN7GT RCA Early New "NOS" | 6SN7GT RCA "Early Smoked Glass". These will also be found with the military designation of VT-231. There is NO difference between a VT-231 in military packaging and a commercially packaged 6SN7GT. The early style RCA 6SN7GT, made during the 40's and early 50's usually have gray glass, so it is hard to see the plate structure. They do have flat black plates. Many believe these early 6SN7's sound best. 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. 6SN7GT NOS RCA Early | $85 ea |

6SN7 Sylvania
6SN7 Sylvania: These vary quite a
bit depending upon when the were made. Sylvania6SN7's produced in
the 1940's and 50's are the best sounding. They have very large
shiny getters at the top of the tube. Later produced
ones are also of very good quality and usually have triangular
shaped plates. Very late production ones have
the "wafer" type base. Even these still beat the
pants off of any Russian/Chinese crap.
