cf)692 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
