You can use a 12SN7 in the 2nd Gen WA6.Thank you for your fast reply!
Well thats kinda sad! wished I could upgrade my drivers more easily.
Wonder if anyone else has WA6-SE with 13DE7's and ugpraded their driver tubes with a positive sonics in sound as a result
EDIT: You'll need an adapter to use the 126SN7 with the Gen 2
The Gen 1 also needed an adapter to use the 6SN7.
