Just got Lowthers, way more efficient than my old standby's. The system is dead quiet with those, but there is an audible buzz with the Lowthers. I realize that DHT aren't the quietest tubes, any tweaks for the DRD Ultimate version?? The voltages check out fine, would dropping the 300B filament .1V help??? PS how long for Lowther EX to break in.
