RE: KT-150 ???

Yes 6SN7 for drivers. I much prefer these to 12au7, more linear, more current, more variety in types.
My Stereo 90 began life as a Stereo 88 which had 12au7 for drivers. I rolled many different types but they all sounded mostly the same to me. Sent the amp back to Rogue for upgrade to Stereo 90 Magnum and was surprised by how much the choice of 6SN7 could alter the sound. I think Rogue took a step backwards when they went back to 12au7 for drivers.
The M-180s are gorgeous amps (I could really use the extra power!). Given the power they produce, unless you are running very difficult to drive speakers you could probably give up a little power to try another output tube.
