I was admiring that especially fine knob wear earlier.
I also had a pair of those same ADS speakers you have pictured there until termites ate them, I think I still have the tweeters and maybe the crossovers stored somewhere if you want 'em. The rest got trashed.
That Halfler stuff is so totally of that period.. the basic geometrical form knobs, the red lettering on black boxes (silver was so old fashioned then), red lights (vs. the current blue LED craze). It was a red & black boxy aesthetic those days. I always liked the Halfler stuff back then. No nonsense.
Looks vaguely like my first 'real' component stereo:
Kenwood C-1 preamp, M-1 power amp, and T-1 tuner from around '83 or so, later stolen which left me absolutely heartbroken. It had two sets of speaker outputs for the main speakers to put the speaker cables in the feedback loop. I bought a fancy Yamaha integrated receiver to replace them, but to my surprise the Yammy stuff didn't sound nearly as nice. That was a formative ear opening experience for me. I still have the 70's Pioneer speakers I used then with some funky looking tweeters (I'll snap a pic) in the back of the room and the Infinity RS4B's I bought to replace them in 1986 that were too big for the thieves to steal.
Halfler surround is retro cool! I used to do that all the time. The Halfler stuff had dedicated connections for it but you can do it with basically any amp (solid state at least). You can use either one or two rear speakers (2 are better, wired in series but out of phase) and driven with the L & R positive outputs of the stereo amp. No ground connection. It basically creates a Mid/Side matrix that sends only the difference signal info to the rear speakers. With a mono source nothing goes to the rears. Nice non-echoy natural ambience effect. I encourage anyone with a couple extra old speakers sitting around to try it with their 'bedroom' or 'shop' system. I wired up a buddy's sign shop last fall with two old speakers and some wire he had collecting dust under his desk to his yardsale amp and he was ecstatic.
