Surprised that I've never explored this thread before.
I sold all of those lines depicted, except Sanyo and Fisher. In the 80's, I was sales manager for the exclusive Sanyo distributor for 5 states. Lots of Beta. We also distributed Panasonic, Magnavox, etc. Discussion of the *80's best left for later...
Quad packages? Here's one we merchandised and rapidly sold out of in our store:
Pioneer QX-4000 w/4 2-way large bookshelf speakers, table & Shure M91e: $499.
As I recall, we closed out QX-4000 for $299 and QX-8000 for $499.
My Assistant Mgr. referred to all packaged systems as "little gyppers."
Receiver was being discontinued and replaced by QX-747, etc.
QX-949 & QX-747's aren't oscilloscopes, but instead light displays.
We also had some great closeout deals on the old '72/'73 JVC black Quad receivers. they preceded the silver & black line depicted in one of the ads here. Built in Eq.
Currently, SQD-2020 and both Technics/Panasonic Quad decks depicted are in use on my systems. So is Akai CR-80-DSS.
That catalog cover brings back memories of selling dbx, Soundcraftsmen, Phase Linear.
We had Marantz Tuner w/scope set up w/dream quad system, 4-DD5, 4 Altec Voice of the Theater horns, Pioneer PL-51 TT w/AT cart. Crank up Stardrive or JVC Quadradisc demo CD-4 and watch jaws drop. We also had the Pioneer scope set up.
Did anyone have issues with Dokorder? We sold them for a week or two, and sent every one back, including our demos. More than half of them had a repair issue instantly. The ones we sold all were boomerangs. Sorry, we have no intention of paying this invoice.
Teac had 2 and 4 channel decks that had suspended meters, too. These preceded 3340, etc. I can't remember the #'s of those, although I recall posting pix somewhere on QQ. I sold a great deal of Teac Quad reels.
Saw/Heard PDQ Bach live w/CSO. I have those SQ PDQ LP's. He also has many Dolby Surround CD's on Telarc. Love Prof. Schickle!
Sadly, we ceased carrying Quad gear by '77.
We had that "blown away" Maxell poster in our tape dept.
Pioneer, JVC, Sony, Marantz all had their midwest warehouses in the next 'burb. So, we'd pick up special orders at lunch. Sometimes, our reps would drop them off.
Those were the days, my friend.
