    When re-gluing a plastic post as you have done here, a zip tie around it is handy to clamp it, and may be trimmed and left on unless it interferes with some other protrusion.

      I use a copper tube of a right size. Maybe it's a bit too much but it's a definitive repair.
      If the screw is loose (thread ripped), just stick a wooden toothpick before screwing it back!

      I have had good luck with using fiberglass mesh drywall tape that i had lying around as reinforcement on plastic things i thought would never hold up for gluing and it has worked surpricingly well, i usually use it with cyanoacrylate glue, i would totally glue that around that post. I just put the tape on and cover it with glue. Im a pro in electronic repairs but i came up with this method on my own by chance, its just something i have used for my own things at least so far and it would be more of a last resort solution in a pro scenario. Using zip tie may certainly be a good option as well in this case, the fiberglass mesh is great in that it can be adapted to reinforce many different shapes of objects as well, you can take off single strands etc.

    • @andrealotito4412
      @andrealotito4412 Před 10 měsíci +20

      an alternative to zip ties i use is heatshrink tubing! once you first glue the broken post together, you wet its surface by cyanoacrylate and quickly slide the heatshrink on it and heat it up. The combination of tightly shrunken tubing and superglue makes it nice and sturdy! if there's enough room surrounding the post you can do it twice to make it even more solid

Since neons need a higher strike voltage than operating voltage, the higher resistance probably impeded that initial strike on DC. Hopefully once it ran a while on AC it got through any oxidation and will work on DC!

      @@kaitlyn__L That would have been quite a Rube Goldberg approach to make a voltage booster just for the track display... I can't notice any flicker, only during track skip, and that is due to the contacts. BTW incandescent lamps do flicker slightly on AC, Mat probably used his camera in 50Hz mode, so any slight 60Hz flicker should be visible - I can't see any. The track display runs on DC most probably. The only benefit of neon lamps in this application would be their longer lifespan, but if the goal is an orange glow like this, an underheated incandescent bulb works just fine, and has a lifetime that exceeds the lifetime of the tape transport.

    I'm a big fan of your videos. May I make a suggestion about measuring belt diameter? Fold the old belt so that it's flat on the table and straight, and measure the inside length in that position. Divide that reading by 1.57 and you have the actual diameter of the old belt. Then order one a tad smaller and you're good to go. This from an audio repair tech who's been fixing stereos since 1977.

    I'm going to go against the grain, but I believe the Lear Jet Stereo 8 is the real "diamond in the rough" device here. I'm sure it would require quite the restoring to get it back to it's intended condition, but comparatively speaking, I'm way more impressed with the engineering of the Lear Jet. Full disclosure, I knew Bill Lear, I was his attorney's son, and I had a friend who had this same machine. The intended design of the machine was to leave it in a semi-permanent location, like a dorm-room. Then, you detached the one speaker and took the player as a single-speaker player. There's missing hardware that would secure the two sides together and would separate by pressing that button on the side. I believe this unit was originally sold as early as the late 60s, which makes it considerably older than the GE, which appears to me to be a Sanyo OEM, and probably has a lot of the electronics shared with a cassette version. Don't get me wrong, if I wanted an 8-track 'boombox' to listen to, I would go with the GE. I just appreciate the engineering that went into the Lear Jet. Great video!

    The reason the tape came out of the cart is that you were playing it upside down. This wasn't a problem with very early made carts because it had a mechanism inside that kept the tape spooled on the reel. Modern carts just mostly re-spool using a guide in the plastic of the tape housing and gravity to spool. If a tape is played upside down, it will unevenly spool and may even jam once it reaches the middle, causing a stuck tape.

    • @stvlu733
      @stvlu733 Před 10 měsíci +1

    When these portable 8-Track players were new they were noted as battery-eaters because of the excess friction of tape feeding from the center. That also made tape breakage more likely. When cassettes came along everyone was more than happy to abandon the 8-Track, and portable players would play 3- 4 times the music off the same set of batteries.

    Hail from Chicago.
    I've had the honor of repairing an early Lear Jet automobile 8 track player.
    Lear himself invented the eight track player. On an early model, It did not have a belt. The flywheel was mounted directly to the capstan that drove the tape and it was also the armature of the motor,it was direct drive.. It was a wonderful piece of engineering. Very heavy and industrial looking. I don't believe the unit was repairable, but to see it in use was a marvel in itself.made in the U.S.A.

    When looking through electronics sections of catalogs from stores like Radio Shack, Penneys, Sears, Wards and countless others (Im sure the UK had their equivalents) Im amazed at the variety of models!!! Always wondered where these designs came from as they varied from store to store. There were name brands like Sony, GE, RCA, etc, store brands, and then just generic names.

      When this stuff was being made it all came from factories in Japan, Korea, Malaysia, Singapore or Hong Kong. The 8-track mechanism came from just a few factories, the electronics were very similar, but the thing that set them apart was the exterior design. Plastic production had replaced most wood or metal and thus, even before computer modeling, it was quite easy to customize the audio devices. There was a never ending array of faceplates, knobs, buttons, switches, etc, all in lovely chromed plastic. Many models changed exterior appearance every year, but the stuff inside was mostly the same. All Radio Shack (Realistic) audio stuff can be found with other brand names, but often with very different cosmetics.

      @@Dave01Rhodes I think he's referring to the pressure pad. They were a piece of foam or felt that's job was making sure the tape properly contacts the playback head. If the foam denigrates with age (And they often do) it can cause crosstalk (multiple tracks playing at once) or loss of audio quality. Has nothing to to do with speed issues thought, If you're having those, it's caused by the player.

    That is similar to how my Dad's reel to reel tape recorder from the 60s had speakers attached. They did latch on better, buy you had to hide the wires inside every time you put it back together. It did sound pretty good though.

    We used to make a concoction of cleaning agent for plastics when we had a computer shop back then. It's just a combination of Wipe Out and Denatured Alcohol. It cleans the discoloration of plastics like that. We use it on CRT monitors. My older brother taught me about that because thats what they use in the company where he works. They service big companies (they are one of the official service center of IBM) that uses POS, computers, typewriters etc. that has plastic housing on the machines

    Another brilliant video, Mat. Makes me wish my parents hadn’t thrown out the eight tracks and the player they had in the late 70s, early 80s. I was too young to object even if I had seen them being chucked, though. I was far more upset to discover that my football cards had been deemed surplus to requirements.

    We had one that speakers that snap together like the one you have but smaller with six inch speakers which sounded quite good because they were insulated well and you could set them 8 feet apart This one had a feature I've never seen anywhere else, it was able to record on to 8 track tapes. We were able to get a blank 8 track tape from Radio Shack, and that was also the brand name that was on the 8-track player. Radio Shack was the go to store for electronics in the 70s and 80s. Great Video.

    The Learjet reminded me that there were a few pesonal stereos ("walkmen") that would come with a pair of speakers to use it as either a mini stereo set, or would attach to the tape player to become a mini boombox. I wonder if you ever stumbled upon those.

    • @thomaswilliams2273

      My parents had a dual cassette boom box and one of the tape players was removable to use as a personal portable. I discovered I could plug something else into the input and use it as an amp. I also had a set of boom box speakers that held a radio you could remove.

  • @tonybossaller4074

    The Learjet unit reminds me of one I used in grade school as a child. And I suspect that’s the most common market where a teacher would set it up for the classroom and not move it much throughout the day/week/semester depending on the class. It wasn’t really portable as much as presentational. I could see that similar to a slide presentation stereo.

  • @jerrygerza7565
    @jerrygerza7565 Před 10 měsíci +2

    The "Lear Jet" design/concept reminds me of the Hitachi TRQ 233s portable cassette player I had as a teenager in the late 1970s. It was from the early 1970s and had detachable flip out speaker "doors". That really looked like a "proto boombox"!

    When you’re sure that a knob has to be removed and your fingernails or screwdriver aren’t up to it, try a pulling on the loose ends of a shoelace fully wrapped around the shaft. The pulling force mostly acts in the direction of OFF. A flat sports lace for very difficult removals has worked for me (thanks to the tape-heads forum who helped me when the big flat knobs on my Revox reel2reel tape recorder wouldn’t budge.

    A much more successful "two speaker detachable" 8-track portable stereo design is one I used to have back in the day - the Channel Master 6201. On this one, the speakers had a metal hinge, could detach from each other, and, for carrying, folded up into a kind of little suitcase. GE made a very similar model - the M8614A

      Matt was saying it was a bit impractical, but there were also many large cassette boomboxes in the 1980s, which had detachable speakers with cables, which you would have to coil back onto the speakers when you wanted to carry them around.

    The portable tape player technology definitely improved very quickly between the early and mid 70’s. I don’t think that market was taken seriously at first, but once the tech improved they really caught on and manufacturers couldn’t wait to outdo each other and make better players.

  • @Jewellerybybarrie

    Brilliant video as usual, I never got into 8 track (although we had a stereo at home with a player/recorder) and I think one of the cars we had did have a player in the early seventies but not as standard. Considering 8 track was designed to go into Leer Jets originally, its amazing how popular they became. I might have to look at getting either a car one or finding a recorder to add to the home system I have just to be completist... That will please the wife no end.....

  • @AudioFileZ
    @AudioFileZ Před 10 měsíci

    Brings back memories. As a kid I used to look at the Allied Radio and Lafayette Radio catalogs and dream about getting a 8-track portable. My dad vetoed it and since he held the pursestrings I never got one. Good things come to those who wait as several years later I had a component stereo system and my folks got me a Wollensak 8-track recorder for Christmas. I think I was about 13 or 14. My first car at sixteen was the perfect opportunity to experience my own tapes on the go. The thing that bugged me most was the track change which would either require expert planning in my recordings or, as I came to prefer due to ease, just let it segue right into the next track with that little glitch in continuous sound. By the time I graduated high school I had to have a cassette though and I got a Pioneer Supertuner one which was pretty good. I actually still love cassettes for probably nostalgic reasons and the fact they were mini reel-to-reels which before all the portable stuff I had a Wollensak 4-track 1/4" recording deck in my component system. There's just something about making your own tapes. Anyone in the US remember Burstein & Applebee Electronic Company? They specialized in parts and close-outs so I got that reel to reel when I was about 12 from them. Those electronic catalogs were my personal Sear's Wish Books! I definitely enjoyed this trip down 8-track memory lane.
