I wish I never entered this field myself. I did it back in the 70's when I was in high school. Everyone thought I was a natural for electronics. What I should have done was get into telecom, but then who knew there was going to be this thing we call the internet back then right. That is the field I am in now, and I would say to anyone looking for a good career, it is the telecom industry. Home phone might not be a growth industry, but wire line is doing just fine in data services like DSL and fiber optics. After 20 years in repair I ended up doing what I should have done right out of school.

One of the most well made VHS recorders ever. Non working machines, usually it's pretty much just a case of change the rubber bits and the lamp, give it a clean and lube and its going again. The loading belt tends to be the first to go and also a bugger to change. Absolute tanks though. They're also good for running tapes through to repack them if they've been in storage with the unloaded ffw and rewind. Sold massively in the UK as the Ferguson 3V30, also seen as the Baird 8930 which was the rental version, both from the then huge Thorn company who had a distribution deal with JVC at the time for video equipment, you therefore see very few JVC branded VHS machines from this time in the UK. The PAL ones were 2 head, SP only as LP didn't really come in until the mid-late 80s. EP is very rare (and terrible quality) as the tape speed for LP is already about the same as NTSC EP. The connections on the back of the UK ones are BNC for the video and 5 pin DIN for audio in and out, this was before we adopted the european scart connectors, although most people would have used the rf output as UK TVs at that time generally didn't have baseband inputs.

When I was a kid we had the Ferguson 3V29 (equivalent to JVC HR-7200 so very similar to this unit), and a Santo VTC5000 (we hedged our bets on formats). Both were well used workhorses throughout the 1980s, and neither required repairs. Fantastically-reliable units the pair of them. I believe these two models were the best-selling VCRs in the UK in the early 80s, and both shared the fact that the tape doesn't spool until record/play is engaged which means the heads run forever. I still have the Sanyo and apart from belts, it *still* has never gone wrong, nearly 35 years later. They don't make them like that any more!

I had one nearly identical, badged as a Ferguson. The only differences were the PAL system of course, only two switches on the left, and the 5-pin DIN socket on the back rather than RCAs. Great old thing it was. It finally died last year and went to a collector. The loading belts were a problem on those, the motor'd spin merrily but the belt slipped. Changed many of those in my time. Lots of these were made under various names in the UK, as the TV Rental companies took them up with a vengeance. Sometimes the little bulb in the cassette compartment went, oh happy easy to work on days.

This was my families first VCR, which we must have gotten around 1981 or 1982. From the comments below it sounds like these retailed for $800. My father was always into getting deals, and I recall he got it from somewhere mail-order... possibly around $600. Of course, that was a lot more in 1982 than it is today. My CPI calculator says $600 1982 dollars is like paying around $1500 2020 dollars. The thing worked for years and years, and I think it was eventually replaced with a newer model in the 1990s with something that supported VCR+, since my mother could never figure out how to program the one from 1982. As I remember the same thing happened with the time display. To me it's interesting to put the price into a more modern perspective. Who spends $1500 on a piece of whiz-bang new technology today? Sure, people buy expensive laptops, but a $1500 laptop isn't really that much functionally different than a $200 one. Both my parents worked for the public school system, so it's not like they had a large disposable income. My dad worked as part of a technical school administration, and my mother a part time ESL teacher. But yet they decided to buy a (relatively) expensive piece of technology in 1982, when VCRs were just first starting to become popular. The other thing I find interesting is simply the revolution that VCRs brought to the world. This was the first time most people could rent a movie at home and watch it. Before that, you had to either watch whatever was on TV right then, or go to a theater. Everything that's come out since then has largely been an evolution (as opposed to revolution) of the market the VCR created. I'd argue even streaming TV is an evolution. That may explain why my parents shelled out so much money for one, circa 1982.

The VCR tape transports that feature the "dropping" pinch roller system (pinch roller below the capstan) have another major advantage. Thanks to the "fork" housing of the capstan (which most of these systems implement), with one bearing sleeve below the pinch roller and one above, the pressure on the bearings is much lower and balanced compared to the "classic" system, where the bearings are below the pinch roller and closer to one another. Also, because the pinch roller pressure area falls between the bearings, it does not cause the capstan to tilt in the direction the pinch roller is pushing, keeping its axis perpendicular to the chassis plane even as the bearings wear down, if the wear is even. On the "classic" system, this tilting effect is obvious and it gets worse as the bearings wear. Regarding FF/REW, many of the cheap later VCRs that feature the "classic" transport rewind the tape fully loaded, while some of the older, better ones which feature the "dropping" pinch roller system (such as the JVC HR-S4700) rewind and fast forward in half-loaded mode.
@12voltvids

That right and that is why I changed literally hundreds of failed capstan bearings on the "dropping pinch roller" mechanisms, and hundreds of broken pinch arm assy when t he grease on the mounting post dried out and the mechanism broke the pinch arm, and usually a few plastic gears as well.The classic design, may have slightly more bearing wear because it is supported from only one side, but then cassette decks, and open reel audio decks were the same design, and that was never an issue. In fact I can't ever remember replacing a capstan bearing on one of these designs, but I remember changing hundreds upon hundreds of Sony, JVC and Mitsubishi capstan bearings of the other design.Not all the dropping pinch roller had a double bearing either. Many had just a conventional capstan shaft like this, just located further back with a dropping pinch roller to allow the tape to remain threaded.

VHS tapes only playback in black and white and the picture quality is very grainy. I can't figure out what happened? I didn't touch anything just replaced a couple belts.

Ahh i did tell you of some of my bodges in the betamax video, using rubber belts to help grip was also one of my tricks too, but i only used it for non sensitive ff/rew/takeup problems. I did see the tape loop out at 7:39, the takeup must have stopped for a second, later on you saw it too, again another typical problem. I never had a special tape tension tool so i would adjust it so the head crossover at the bottom of the screen looked vertical and clean, tracking/headpole adjustments too.

All 4 head machines use 4 separate heads, it is just on earlier machines they were located on physically different positions of the drum. Then came Hifi that needed the hifi heads a specific distance from the video heads. They then moved to a dual azimuth design with the 2 heads glued to the same mount. The A SP head would be have the B EP head, and the B field SP head would have the A field EP head. For machines that had LP, which was never a reconized speed by JVC, they used the EP head for that speed, which did not improve the picture quality of LP. It probably made it worse as there you have a skinny track with a bunch of blank tape producing niose on each side of the track. That was the idea behind 4 head machines. So you could have a nice wide gap for the faster speed, and a narrow gap for the slower speed to optimize performance.Music was Jean Michele Jarre. He performed Oxygen and many of his other stuff for a concert put on for the Royal Wedding on Monaco.There is a stufio release of him performing that album live, and it took 4 musicians each with all the same instruments he used to make the original album that he recorded in his basement something like 40 years ago. Instruments that many have never heard of like a Mellowtron, Therimin ect.

I have quite a few vintage tube radios that I do not run for that reason. That's the same reason I don't run my Macintosh receiver because the four output tubes have not been available since about 1980. Sure it can be modified to use an el34 or a 6l6 but changing the circuitry to use modern tubes one will change the sound and two will make it not authentic and therefore it's lost its value. Since my unit has all original tubes I won't run it because I don't want to wear the tubes down. Plus it was my dad's and for sentimental reasons I want to try to keep it in working state unfortunately the cabinet looks like crap because when my dad bought this receiver new in the late sixties let's just say my mother was not too happy with him spending that kind of money on a stereo and she told him to take it back, whoever the store wouldn't take it so he put it in the crawl space and it sat there until I found it in the 90s. By that time rats mice had gotten into the box chewed the power cord chewed the wooden cabinet and made a real mess of the unit they didn't get inside electronics but they did make a real mess of the wooden cabinet which would all need to be redone and restored.

In the early days there were few manufactures that built expensive VCRs. These core companies, Sony, Hitachi, Panasonic and JVC built heavy high quality VCRs out of strong beefy metal parts and quality semiconductors, many of which were made in house. You paid for this quality, and early VCRs were in the 2,000 and up price range. This at a time when the minimum wage, at least in Canada was 3.00 an hour, a new car went for 10 grand, and a new house 100,000. So 2000 for a tape recorder to record TV shows and watch movies was out of reach for a good percentage of the population. In order to sell VCRs to everyone, the companies started contracting out assembly of their machines away from Japan, where wages were high to countries where labour costs were much cheaper, and that 2000.00 VCR quickly dropped to 500.00 and kept falling. This was from using plastic parts instead of metal, and moving to robotic assembly where parts are just stamped out, and clipped together. The PC Boards were contracted out to other companies for parts placement. The result is what you asked for. A low quality cheap machine that will last long enough for the warranty, and anything else is a bonus.

I don't know of anyone even local that still works on video gear. I get stuff from all over the country shipped in. Everyone i knew has long retired from service. I did too , 20 years ago and then about 10 started working on a few pieces a week to keep the mind sharp. I do it now just to teach practical repairs to viewers for those interested in this old stuff. Nothing makes my day more than someone sending me a message telling me their fault was the same as one i demoed and they got their unit working. Of course when that thanks comes with a "tip" of appretion it really makes my day.

@@12voltvids Many thanks for the reply. Unfortunately, I haven't the ability to do the repairs myself. I wish I could for all the old AV equipment I have had over the years.

Rubber bands will eventually crack, or turn into a nasty gooey like substance, as the years go by. Hopefully that is a temporary fix. Nice videos nonetheless!!!

I put new belts in before I sold this old beast.

That's interesting, i've done intense research about the history of videotape recorders, vhs and betamax, and i have never read that Sony invented the original M loading system. You were a repair man for Sony, isn't that right? So it might just some information that never surfaced in the web, not that i have seen.

Sony, when they finally did make the change to VHS even advertised that they were the co-developer of the format. There is lots of info out there. I just found this: "In September 1976, JVC announced the VHS-format VCR to compete head to head against Betamax. With this announcement, the VCR format battle began. The JVC product boasted two hours of recording time twice that of Betamax. The year before the Betamax release, Sony had approached Matsushita and JVC, its two partners for the U Format, about unifying product specifications. At that time, Sony had disclosed information regarding the Betamax specifications and technology to the two companies. In response, Matsushita and JVC delayed any decisions about unifying standards for a year. After Sony announced the advent of the video age and followed this with an aggressive sales drive, JVC began its own highly effective advertising campaign. Sony took a closer look at the VHS format and everyone was aghast. The technology and know-how that Sony had willingly disclosed when it proposed the unification of the U and Beta formats was incorporated in the VHS format. Although Sony had freely given the two companies access to its basic, patented technology, it was impossible for Sony to hide its shock and surprise."Basically what JVC did was take the design, and change it just enough so that it was not infringing on patents. They couldn't use the U loading system, so they basically turned it sideways and used 2 threading arms to achieve the same thing.Incidentally, the original 8mm cameras used the U loading, and then later cameras changed to the M system as it was more compact. Sony would NEVER have been permitted to use the M loading design on their 8mm cameras if JVC had a patent to it, but they didn't because it was the first design before Sony settled on the U loading system for Betamax. The reason they went with the U system was it had fewer moving parts. Basically 1 loading ring as opposed to 2 that turned in opposite directions, which the M system initially had.

I really like your videos and your work but the rubber belt maybe not the best idea. I think it will degrade over time and crumble into your machine.

This is not a machine going back into service. I just wanted to get it running for the video. I did explain that this was a temporary solution to get a machine back up and running for a short term fix. This is done quite often in the broadcast world say when a turn table broke a belt, or a cart machine belt started slipping and the engineer didn't have a replacement on hand. That is where I learned this trick when I was in broadcast, and we were out of a remote shoot and a belt started slipping, or broke. The field engineer would whip out his box of rubbers (pun intended) and make a quick fix to get the production in the can, and then once we got the production truck back to the studio would pull the machine into the shop and do it right.Since I am not planning on using this machine any time soon I am not about to spend 20.00 or more on a belt that will just sit there. If it was a machine that I was planning to use regularly then yes I would, but this was more to look at the old unit, and see if it would work after sitting unused for many years. This unit probably hasn't seen power since the mid 80's as I upgraded to hi-fi decks when they first came out. I only hang on to this old unit because I like to collect old pieces of technology, for nostalgia. Who knows some day it might be worth something. I once rented out one of my old Betamax units to a film company that needed one to use as a prop for a film that the period was early 80's. It was actually the SL8600 that I recently fixed, screws missing and all. They just wanted it to sit on a shelf plugged in with the clock light up.
