They had one of those Muzak machines in the office at my first job, an old specialty grocery store. Only the manager was allowed to change the cartridge.
Unfortunately, none of the managers ever seemed to care that we were listening to the same 6 hours of adult contemporary every shift, all week.

Every time I was cleaning the floors or talking to the management, I would try to see the cartridges, to at least read the titles that were printed on the label. To this day, some of those dumb songs are still stuck in my head and I have no clue what they are.

Revere Tape Cartridge

I have a working Revere tape cartridge machine. Here is what a machine and player looks like:





The machine is a reel-to-reel machine. One reel is in the cartridge and the other reel is in the machine. The cartridge self-threads, starting with a wide, stiff leader that feeds in and registers with the take-up reel in the machine, then the leader drops to the width of the tape, and finally the tape begins to play. When the end is reached, the tape is rewound, back into the cartridge. The machine has an input stack, and an output stack. You can stack as many up as you wish, in the input stack. The mechanism is a real Rube Goldberg, but the idea is quite cool. Being early 60s, the electronics are strictly tubes. I especially like the cat eye amplitude indicators. My machine is different than the one above, but is is buried in my inventory stacks at the moment. I even have a few blank tapes for recording on my machine, still in the original bubble packs. I have several commercially recorded tapes, and they did do a good job producing them. They sound quite good.

Enjoy,
Rich P

3M Cantata Repair here

In the late 1970's or early 1980's I used to repair these 3M Cantata's. They would be completely taken apart and all parts would be placed in an ultrasonic cleaner filled with denatured alcohol, then I would go outside for a cigarette or 2 and come back and inspect all parts and reassemble and lube these units. They have a unique mechanical timer so the unit would operate continously or switch off and on every 20 minutes if I remember correctly. They actually had a mechanical fade out/in pot. 1 7/8's was the speed and did not sound too bad when tuned up and was for commercial background music, for legal commercial business use. Federal copyright law can go after any business that plays music and these were lega as you paid for the rights to "broadcast" this music in you place of business.

Background music studies had shown that the tempo of the music, based on human heart rates, could directly affect shoppers at the subliminal level.

Quite the mechanical engineering.

Pure Sinewave, how reliable were these units? Did you see many come back for repair?

3M Cantata

I just started renovating one of these players. I had bought four of the cartridges but took me a while to find a machine. The one I got, like mentioned by other owners too, has pinch rollers that have turned to tar, I will have to fashion new ones somehow.

In the meantime I took the tape out of one cartridge (which requires repairs in any case) and tried playing it on an auto-reverse reel to reel. Interesting that even though tracks are laid out the same as regular 4-track, they are reversed in direction music was playing backwards on all four tracks. I wonder if that was intentional to prevent playing on unauthorized machines? (In the end I made a MP3 of a portion of the tape, then used a program to reverse it. Sound is good, for 1-7/8 ips).

The machine is a mechanical marvel. As mentioned further upthread, it even has a gear controlled volume pot, I am guessing, to turn volume down between track changes.

The auto-reverse works by using different pinch rollers on the same, clockwise turning capstan. The reel drive too always runs in the same direction. Which reel turns in which direction is controlled by the capstan. Reel turntables sit on felt slip pads and depending on which way the tape is being pulled by the capstan, take-up reel turns with the drive, the supply reel slips against it.

For such an expensive machine (like $3500 in 2017 money) though I am not sure why they chose to use a single mono head and move it up and down mechanically rather than two stereo heads and switch them electrically.

It will take me a while to figure out what does what, goes where before I get the courage to take it apart!
