I've decided to temporarily retire the old Scott until I can figure out what's going on. The right channel gets downrigh hot, the left only warm, but everything measures the same on both sides. Wierd. Also, the left side is a bit "duller" sounding than the right. I've dug out my old Fisher 500C receiver and am using just the amp/preamp section (see posts above.) The Fisher actually sounds somewhat nicer on my old EV LS-8 open baffles. Highs are smoother (softer?) and bass a bit fuller (a good thing with open baffles.) It sure looks ugly, though. Oh well, I guess it's hard to have it all.
