LOL jhl........
Mini WA22....I've had my WA2 since 2009 and was communicating with Jack on the WA22 before it came out...He confirmed the 6SN7 driver but I already had a balanced setup so I passed it up.
There is just soooo many tubes to try in the WA2. The 6922 is an awesome tube and I have tried many from the globes to the reflektors. I also have a hybrid that uses 6922/6DJ8 so I have tried a lot.
It's time to go to the dark side. The 6922 is not the end all be all.....I am an adapter freak and have tried many tubes in many different amps. The 6SN7 takes the WA2 to another level as well as other off the wall tubes. You should check out the DV336SE thread (Part II) I started over seven years ago. We cross reference tubes with adapters with the Elise and WA2 and DV. If it works with my 6CG7 adapter, it will work in the WA2.
This setup I'm listening to now will rival any 6922.
JAN-CRC 6AS7G power tubes and JAN-CHS 6SN7GT VT-231 drivers.
Come to the dark side guys.......A big wide world out there...Give the 6922 a rest. I have tried many driver tubes in the WA2.....My TS 6BK7B will put the '75 reflektors in timeout in a corner with nowhere to run.....I paid 12 beans shipped for them..Time to expand the horizons fellas!!!!!
Cheers!!!
