After reading some of this i went to my storage building and dusted off a languishing 60's Fisher KX-202 integrated amp. Actually, my intent was to try and localize the problem that caused me to put it away so I could bring it in to a tech.
Wellll, the fuse holder was loose, THAT's what was wrong. Blush.
I confess, I never paid much attention to the hookups & knobs, but lo & behold it has a center speaker output with a widely stepped attenuator...maybe 8 positions. So I'm going to experiment with an old Sansui speaker before I start looking for a Belle, LaScala, Heresy, Cornwall, etc.
BTW, the Fisher sounds pretty darned good. A bit more forward and punchy than the Jolida 302b I've been using. Bigger in the mid-bass and tighter in the low bass. The phono section sounds pretty good, too. Full-function, tape monitor, etc, doesn't hurt either. It uses 2 7591's per channel and I'm guessing it makes 20 or so watts per channel.
