6SN7 / 5692 Tube List
This 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

These are Red Base 5692's made by

just different branding on them. Since many of these
manufacturers did not make their own 5692, they bought them from

| 6SN7GT RCA Early New "NOS" |
6SN7GT RCA
"Early". 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.

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.
