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.

Q) Why are there comments from a week ago when this video has just gone live today?
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.

  • It's actually a wonder that any engineer all those decades ago even created something so mechanically/electronically complex!

  • You say you found it difficult to get your head around how it worked, But what I always think about when working on an old electromechanical device like that is "I've got the easy job of just trying to see how it works....... There were some poor sods who originally got tasked with thinking out an entire mechanism to make some marketing guy's idea into a real thing". Some of the later electromechanical machines I've had apart have been truly spectacular with their Rube Goldberg level of complexity. With no real electronic controls to speak of, all the logic within the devices had to be done via mechanical means. Some of the convoluted ways engineers had to come up with to do, what now would be seen as a simple task, used to make me wonder how the device could ever have been reliable enough to be classed as a "Finished product" even when new? Today engineers can most of the time pretty much do the same job, cheaper and more reliably, with a couple of stepper motors and less processing power than you'd find in a cheap digital watch ! :)

  • Have you ever thought about recording audio ( particularly long radio shows onto DVD. In ep mode you can get up to 6 hours. Plus a timer function is there. if you use dvd ram you can also edit. One of the best machines to use is Panasonics first dvd recorded the DMR E20. The reason this one is better is because it does have a VU meter on the display. They can be found on eBay from £5 to £50. Also please check out my TV repair channel here. Keep it up.

  • If you don't have one, you are in desperate need of a tool called a "spring hook" considering all the fiddling you do with old electronics consisting of belts and springs. Until I worked on copiers for a living, I had no idea such a tool existed, but once I become aware of its existence, it became an irreplaceable tool for dealing with both belts and springs. I am adding a link to show you what I am referring to, and the type I have is nearly exactly the same as this save for the lack of the black grip material on the handle as mine is simply knurled steel. It's called a "push and pull spring hook" if you want to look them up, and they generally cost little more than a few US dollars; mine was a bit pricier since I bought it in a brick and mortar store for about $9 USD back in 2010, but I'm sure you can find them for cheap online - the site in the link is selling them for $3.60 USD at time of posting, but I didn't look at their shipping costs. Definitely look into getting one if you don't already, as they will make doing work like this IMMENSELY easier. As a side note, you can also get a spring-loaded "grabber" variant that will hold onto the the spring or belt with the hook under tension for springs and belts that are difficult to place, and I'd be happy to share a photo or link for one of those as well if you are interested. Here is the link showing you what the tool looks like that will make placing belts and springs far easier than using needle-nosed pliers or a screwdriver:

    Justin KashtockJustin KashtockVor 2 Tage
    • For reference, the spring loaded spring hooks are proving difficult to find an image of, but "IC Grabbers" are essentially the same thing and look like this: It is, for all intents and purposes, a little hook under spring tension that you have to press on the non-hooked end to release the "grabbing" tension of the hooked end, and they are good for moving springs and belts into exact locations that using a spring hook alone cannot accomplish.

Worked like a charm, no problems with the ski slope at all. Still the coolest cassette player I found in the scraps then was a Bang and Olufson Beocord 5000, absolutely amazing cassette recorder for the time; peak VU meter using bulbs (no LED's at that time), dual capstan and dual motor (no clutch!) and build like a tank weighting in around 8.5 kilos!

  • By the way...watching you amazing videos I was thinking about a cassette tape emulator. I've checked out only yesterday...and I've found wireless (with battery inside) Bluetooth fake cassettes that could receive audio stream and transmit it via the magnetic head, etc.. It would be interesting if you could test these cheap things, measure the noise and frequency range and see how good they are. Some of them have working spools inside (no tape though), they look amazing, although they say the battery is a bit weak. But it could give a true hifi experience via a tape deck eliminating "wow and flutter" and for the first time we could hear how good is the audio circuit in a cassette deck.

  • It's weird they didn't just use a stepper motor to move the head down by a track, and use another stepper motor to reverse it. This seems obvious (although perhaps more expensive) but at the same time, look at the ridiculous complexity of this design? Also, it looks like at least a 4 tape delay before the 2nd side of the cassette played with a maximum of 7 tapes - maybe 8. God, I don't miss this stuff a bit. It's all hacks and jerry rigging. I'm surprised I'm not seeing twist ties and duct tape in this product - new out of box.

I agree one hundred percent on that - but I still really enjoy your videos of some of the more odd equipment put out there. I, like you also enjoy tinkering on this stuff, and unfortunately for me, I currently have four not quite working cassette players that all need various levels of attention - some of which is beyond my (current) skill set.
