Philips crazy Ski Slope Cassette Deck

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

Bi-colour Tapes from www.tapeline.info
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.

A) Patrons usually have early access to videos. I'll show the first version of a video on Patreon and often the feedback I get results in a video going through further revisions to improve it. e.g. Fix audio issues, clarify points, add extra footage or cut extraneous things out. The video that goes live on youtube is the final version.

    Ampex had one fairly similar to this one from the same age. I almost bought one, already used and broken even way back then. don't know if it could do the flip trick or not. May have been the same mechanism even...

    About the old belts being fine - my grandpa gave me an early 1960s Sony TC-900 reel-to-reel (small 3 inch) recorder, it was never maintained and last year, when I took it apart because the mike input was oxidized (pitch black contacts), the belts were still in good shape. He also gave me a Dual turntable with the original invoice from 1974 and it's still going strong, never been lubricated during his course of ownership. The trick is probably to cover the machine with a rag, which is a practice older people used to do, therefore dust and other contaminants don't get in. R2R machines and early tape players were built like tanks - all steel, heavy duty belts, giant capacitors, but the downside to that is the very complicated mechanism, those guys are a nightmare to repair, it usually took me many days, but I never gave up and all of those 60s/70s devices under my bed are working now.

    Without a doubt, this has got to to be the most complicated cassette playback device ever devised. This is engineers having fun, sitting around a table, taking a shot each time someone comes up with a more complicated way of doing something.

    Incidentally, the low audio volume you have is almost certainly the germanium transistors in the amp. These develop an internal leak to the metal case. If you are curious, as a temporary test you can loosen them from the heatsink and test, you may well have full volume restored. These transistors can be hard to find but a workaround is to give each one an isolated heatsink if space permits.

    32:24 the Dutch sign says: Cassettechanger for 6 cassettes. After feeding back, the other side will also be played. So you where right about the 6 cassette, weird that they show it with 7 cassetes in the pictures.

    I could swear I saw a Techmoan video with a somewhat similar mechanism but it "shot" the cassettes out and used top corner of the slope to flip the tapes. I can't find it now though... I'm sure I didn't imagine this. My description probably sucks, but if anyone has any ideas what I'm talking about I'd love to see this video again.

    Maybe I'm silly, but when I saw that ad for this tape player in your original video, I assumed it was showing a tape being *fired* up the ramp at high speeds. I didn't think it was actually 6 tapes at different points on the ramp.

    I get the impression this was designed by someone who was used to record changers working through a stack, and didn't think of flipping the head or spinning the tape directly because that idea wouldn't apply to records so hadn't been thought of yet. Funny how cassettes are such a long-lasting medium so we see generations of different attitudes applied to how to play them, while the tapes themselves stayed basically the same.

    You are pretty good at getting these old devices working. I hope you will find this helpful. I recommend getting real spring hooks, both a pusher and a puller. It makes much it easier when dealing with springs and drive belts, and other things. They aren't expensive and work much better than something you make yourself. I know since I tried to get along with out them for a long time using whatever I could cobble together.

    I used to own the N2506 DNL (dynamic noise limiter) cassette deck pictured at 31:28. It was my uncle's before me and he gave it me when he bought one of those new fangled all-in-one music centres (just before everyone changed their minds yet again and decided having separates was better after all!) When it inevitibly went wrong, I took it apart and couldn't believe how vastly over-engineered it was. For example, see that recording level slider on the right of the unit? If you think it's a fader, think again. The slider moved along a greased cylinder with a spiral cut in it (looking something like a barber's pole) at the end of which was a standard rotary potentiometer. I think Philips engineers must have been paid by the number of components they could use in their designs!

    Is it possible that fully loaded (long play) tapes would have worked better due to their weight of full spools? Those metal tapes were noticeably heavier than the cheaper tapes. Or so I've heard. lol
