Philips crazy Ski Slope Cassette Deck

As unusual cassette decks go - the 1970s Philips changers are some of the oddest.

Bi-colour Tapes from

It’s very likely one reason the tapes didn’t always locate perfectly in the mechanism is because I was using short custom-wound tapes. As these have less tape inside...they will also have less weight than the average C90. When I ordered them I had no idea the tolerances in the machine would be so fine with regard to tape weight. My intention was to use the short lengths to demonstrate the continuous tape recycling feature activated by the tape end sensor...without having to wait for a full length tape to reach the end. In addition most new cassette shells are a bit rougher and more angular than ones from back in the 1970s - they'd be more smoothed off with rounder edges, and as a result they'd be far less likely to get caught up against the sides of the cassette well.

    There is a MP3 player that goes directly on a regular cassette player. All the micro-usb sockets are recessed into the tape themselves and it plays music straight into the cassette magnetic head... get 6 of those with 256GB microsd cards and you got music for quite a while, until the mp3 players run out of batteries.

    Would be an interesting feat to reverse the motor polarity so the tapes would play backwards. xD

    This is the mechanical equivalent of legacy spaghetti code: a lot of fiddly parts that work okay on their own that have been very carefully mashed together. When they're all working it's a thing of beauty, but it takes just the slightest bump in the wrong place for it quit working, then good luck figuring which fiddly bit is interfering with which other fiddly bit in the wrong way.

    Rather than create a solution to a problem, this is more like creating a problem and then designing a solution. I don't think I've seen a cassette player more likely to self-destruct if two buttons are pressed at the same time!

    This would have been AMAZING if they had an auto reverse feature. That way you could listen to the entire cassette (both sides) before moving on to the next one. Edit: oh, you already said that…. Note to self; watch the entire clip before commenting. 👍🏻

    As far as the right only low output, I suspect the control knobs having oxidation in them. I recommend exercising the knobs to see if anything changes you may find that it crackles and jumps in and out as the wipers scrape away some oxidation. If there's progress, using a liquid de-oxidation/contact cleaner could finish the job. Keep in mind re-oxidation happens fast if you don't clean out the slightly corrosive (because that's how they work) cleaner and apply a lube/protectant. These high-end machines of the 70's and early 80's are tanks and often don't need too much electronic repairs, It's the mechanicals that usually need maintenance. Having said that, some 'philes like to re-cap them and replace opamp chips and or transistors in the audio path to make these machines sound even better than when they were new!

    I noticed that counter seemed to move too fast foe a cassette player. You found the reason, It was around the wrong part of the wheel, therefore it was running too fast due to the size of that part of the wheel and falling off because that groove isn't where it is supposed to go. Good, if difficult diagnosis! All repairers are tinkerers. Don't sell yourself short. That was a tricky one.

    I lived in Stockholm in 70;s and remember this devices from Phillips and DUX in Quelle catalogue of those years. It was of a price about 700 kronos which was a quarter of monthly salary of mid class man. For the same price you could get a good music combo with turntable, cassette recorder, tuner, amp and speakers - even with ultrasound remote!! Hence there were few families who would prefer this construction against a hi-fi combo from a same brand.

    I had a tray 12 cassette automatic changer from 1973. It wasn't a very good sounding machine, but it worked. I ended up using it at the college radio station where I would load up old shows I did and let them play all night after I left the station. I don't remember the brand and never saw anyone with something like after I was through with the deck.

    To play both sides purchase 2 of same tape with null cassette (would instantly advance to next tape to play side 2) loaded in between. I believe Philips sold their own tapes which would have been good gimmick to sell more pre-recorded tapes. BTW FWIW I have "Realistic (Radio Shack Cat No 44-223) Cassette Tape Hand Winder" (allows one to manually re-wind cassette faster (10x?) than machine). which is of same dimensions and just held by hand against cassette face to operate. Also have several Maxell Capsule cassette tapes (I think where known as "soft shells" State side which were available in non-conventional lengths, ex. 80 or 110 minutes to better match actual album time length) which have all long edges of cases rounded over claiming gals could carry their tapes in backside of bikini bottoms without having sharp edges digging in.

    On the subject of replacing belts, the U.S. company TurntableNeedles has a special belt replacement tool. I'm sure it's available elsewhere as well. It is a metal rod with a blunt hook on one end for pulling belts and a blunt notched mechanism on the other end for pushing belts. I've found it really helpful in the past. Again, everything is blunt, so there is no worry about accidentally cutting belts. I recently repaired an Elcaset EL-5 machine which was very cramped inside, so I had alot of difficulty reaching the wheels with my hands. The machine even had a piece of old belt stuck to a wheel that was in a hard-to-reach position. The tool worked great for this job.

    Out of curiosity, any chance you found out what they charged for the ski slope attachment? When I saw the thumbnail for this video, at first I assumed it only played one tape at a time and some giant solenoid slingshotted the tape through the ski slope to flip it over..

    Two things. Tapes in the early 70’s were a lot shorter duration than 90mins. Secondly the tapes you are using weigh less than a full length tape and so won’t settle into the machine properly.

    am i the only on who noticed that the main reason they would get stuck is because of the little notch at the bottom of the tape. when all the tapes are stacked with the notches stacked on top each other it caused one side to be a little bit higher than the other. that corner blocks the tape sliding down the ramp also... why am i watching this

    This reminded me to look into a cassette deck I had back in the early/mid 1980s. It was an Onkyo and when you put the cassette in, it would pull it back about halfway into the machine. I know it wasn't just under the Onkyo name but I've yet to see one(in person) since the 1980s when mine finally died. Any chance you know which one I'm talking about? I looked and haven't seen anyone do a video on them as of yet.

    36:30 A sollution for this would be like this. Say we have Album A, B & C, side A & B of both. Instead of tape 1: AA & AB, 2: BA & BB, 3: CA & CB, you'd record them as 1: AA & BB, 2: AB & CA, 3 BA & CC. Then the playorder would be: AA, AB, BA, BB, CA, CB as it should be. Having that said, you would have to have sets of tapes, since if you add one more tape, you have to make another set if you would have it in order.

    I wonder if that recording protection mechanism bar originally had a small plastic wedge on the end inside the cassette box. The wedge would have been small enough to fit into the square record protection hole in a record protected cassett and the wedge shape would allow the bar to be pushed away from the cassette when the eject mechanism moves the cassette toward the collection bin. Just and idea but maybe a non-starter, because that would probably require a recess in the cassette bay for the wedge to move into.
