How to bias Sonic Frontiers Line 2?


I'm planning of changing the six tubes in my SF Line 2 preamp but the manual doesn't say anything about biasing.
Does anybody know if this kind of preamp needs biasing or is it auto bias? BTW I'm using the balance input and output.
Thanks in advance.

You can still get schematice from Anthem (Sonic Frontiers) for $25 the last time that I checked. Just e-mail them and they'll get back to you.
