Herman thanks for the reply. I'm not sure how this pre is wired. The first owner suggested I try switching the spkr leads so I assume this is a common cathode you decribe. I do know when I did this music comes from EVERYWHERE now. This is one sleeper of a pre. Now on with the rolling. BTW I just switched the pwr cord from a old Synergistic Research alpha to the Stealth HAC I had for awhile. Did I say a sleeper--hey it just woke up.
Question on twin triodes
I was told that twin triode tube pre's invert phase. Although my current pre (soundstage two) does not state this I did change the spkr leads just to see. It did make a difference--sounds a bit fuller all around. Bass is very good for stock jan philips tubes. My amp is a Tim Rawson bpa 300. Always learning in this hobby. Enjoy the music.
