according to this http://line6.com/sup...ew/thread/75238
multimeter to DCV 200m
AB mode and you should get a reading close to 25.0. If it's off, turn the adjustment screw with a small screwdriver until it is at 25 +- 3
Like one guy in previous post I'd like to try JJ el844 who have 25% less power cause my DT25 is still very loud.
Should I bias -25% (18.75) like I read on other amp site or I stay at 25?
