7308 where offered Valvo I belive as a factory upgrade.
The 7308 family of tubes is a premium build of that family 6DJ8 6922.
NOS 7308 will out perform most 6922 and 6DJ8.Maybee not all but the build specs are much better in the 7308 tube.

I had an Anthem CD-1 that went from good to very good to great.
6922 to start Valvo 7308 then to an Amprex 7308.
I also had an Anthem CD1. I tried Sovtek's but they were
pretty dull however the best one I used are the Mullard
'old stock'."Alternative Audio" in Dundas,Ontario still has
a few left.Sweet tube !!!
I had a pair of RCA tubes in the rear most bank only, with stock Sovteks in the forward 2 banks and was impressed with the sound...more warm and detailed. The Sovtek was vry clinical and harsh IMO in comparison. I have used Amprex and didn't notice much difference between them and the Sovtek. I have tried Siemens and Telefunken in my Amp 2 amp, and really liked the changes they made.

I'm new to tubes, and didn't even know I could use 7308 tubes instead of 6922. Is any1 sure they are interchangable in Sonic Frontiers gear, or is not gear dependant?
