I started out with a beautiful Pioneer 100w 2-channel receiver,
Wow! You are now really shaking loose some memories. In the mid '70s I went into debt for a Pioneer amp/tuner that I came across at The Stereo House, a business long gone, one which had stores across north central and northeast PA. (Anyone remember The Stereo House?) That unit had four channels, and each and everyone of those channels had its own 100w amp.
While we're at it, anyone recall what "sound" retailers used to operate in NE PA?
Marantz was once a huge name, HUGE. How about McIntosh stereo gear? Their big draw, way back when, was that they were about the only USA stereo manufacturer. Am I nuts, or did McIntosh have a plant in the Binghamton area? Seems true audiophiles (circa '70s/80s) adored McIntosh, and pretty much thought everything else was junk. In fact, Pioneer was kind of way down on the list. How about Radio Shack's Lafayette line?
A friend of mine had a small Lafayette amp, no tuner, just an amp - on/off/gain, bass, treble - that was it. Off of this box he was driving a pair of Lafayette three-way speakers (floor models) through which he was pushing vinyl on a Lafayette turntable. I think the whole rig cost him a whopping $180 or so. It sounded like a million bucks.
While I'm stumbling down memory lane, I just recalled having an FM antenna (an omni type?) from Radio Shack that I installed on the porch of an apartment I had in Scranton's Hill Section. I pretty much mounted it on the nearest piece of wood, then ran some old TV antenna wire I had beneath a closed window and into the back of my amp/tuner. Remarkable the reception that thing gave me. I swear I was grabbing NYC stations like their horns were five blocks away in Nay Aug Park. Could be it was more a matter of elevation than the antenna. The apartment was a block from what used to be called Chapel Hill, the highest point within the city's limits.
Memories. Ain't that what Christmas does to you?
