6922 vs 6SN7 - Page 12

Bob Richards · 24th April 2011, 03:11 AM

I like the 6SN7 better than the 6DJ8 just because it's better able to handle heat, so should last longer. I've seen linearity comparison tests done by top people in the field that showed that the difference between these two tubes was dam small, but I've also read in forums that 6DJ8's often have noise problems. I also like the mechanical rigidity of the 8 pin octal socket. It seems sturdier. Maybe it's more nostalgic too. It would be awesum to have some of the early 5 and 6 pin tubes like the 27 and 76 (extra nostalgic to me), but I'm not willing to compromise on any of the specs, plus being single section tubes would take twice the space.

High transconductance tubes like 6922 are not good for sound...

i set aside my 7N7 preamp for the 6H23, they sound the same to my ears, the 6H23 operates at a B+ of 60volts and 4.7k plate loads in a CE/CF config....

my 7N7 preamp uses a B+ of 300volts and has 28k plate loads in the same config....

I still don't get the "versus" thing. Different tubes for very different applications.
