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.

Special Deals

Here are some recent purchases I've made that I will have on special as long as there is good quantity on hand.  So, get 'em while you can!! There will be more soon.

 

 

 

5692 Red Base

Type

Description

Price

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 branded 5692's
$125 each

matching available at $5 extra per tube

5692 Red New These are Red Base 5692's made by RCA under different brand names such as Westinghouse, GE, Sylvania, etc.  They are absolutely the same as the RCA's, just different branding on them.  Since many of these manufacturers did not make their own 5692, they bought them from RCA.  "NOS" 5692 Red $100 ea

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.   6SN7GT NOS RCA Early $65 ea
