The control goes from about 7:30-8 o'clock (lowest) to about 4:30-5 o'clock (highest). The problem begins to go away at about 9 o'clock, so it occurs at the lower settings, during low level (everyone else in bed) listening levels. I had some balanced Endlers laying around (-10 dB) as well as some balanced DIY in-line attenuators (using Vishay's) that I had used with a preamp years ago. Using these gain reducing devices in-line pushes the volume control up into the range where it tracks well, even at lower volumes. Of course, as Elizabeth suggests, my solution will be to work this out with the seller. In response to 6550c, it is a SS pre. Thanks all.
