I bought that machine when it first came out. It was over a grand. It was an absolute BEAST! I used it daily to record/play my favorite shows for almost ten years, with no problems. That was at least 2-3 hours/day for ten years. It had one problem: Now and then it would snap the tape off after rewinding! You may note it does not wind down at the end like the next models did.

Boy you’ve got more patience than me to work on that thing! I owned a later model JVC VHS (not SVHS) that had those dropout issues and had the same service done to repair it. Mine also had an issue where the remote would stop working after so many minutes. Was sent off to JVC for repair and returned saying they couldn’t find an issue. Plugged it in and same problem. My local service dealer found it was a bad trace in the circuit board that when you lifted the corner of the VCR it would work and stop working as soon as it was set down. I eventually sold it figuring I wasn’t waiting for the next issue. I eventually bought a SVHS Hi Fi HRS-9500U that has given me good service until recently when fast forwarding tape and putting into play mode creates slack and spills tape into the machine . But it’s an old machine and has been stored for the most of its several years with little use so it’s to be expected.

Man, you are NOT wrong about JVC. All my VHS decks are pro/industrial models (SV0-5800, that kind of thing, all with plug-in circuit boards), but I needed a relatively high-quality deck for EP tape playback (EP makes me want to weep, but we get all sorts of archive crap on VHS that we have to turn into 1080p ProRes for tv documentaries and so on). So, I bought a BR-S378U. Outwardly, beautifully made. Once the swinging pendulum rew/ff gear was cleaned/lubed it was working great. But then I noticed the hifi audio was rather low and slightly dull-sounding. Probably caps in the hifi circuit. So I begin disassembly....YIKES...what an absolute DOGS DINNER. Boards all over the place, spaghetti everywhere. You can't even open up the main board without dragging a bunch of sub-boards with it. Truly the worst design I've EVER seen. Come to think of it, the old BR-7000 duplicator decks were a spaghetti mess too, but at least the boards were somewhat accessible. This "prosumer" JVC is HIDEOUS inside. "Nil Points" to JVC, as they say on Eurovision. Thank god I usually only have to work on professional equipment! I'm amazed the BR-S378U even powered on again after the trauma of disassembly/reassembly! Ughhhhhh!!

At least this one is not disintegrated yet. I have a Hitachi S895 S-VHS from the same era, similar board count and wire spaghetti (although it's more tidy with more connectors, the front comes off with zero wires attached to it IIRC), and every single board has a lot of leaking capacitors, all the boards are corroded to hell. I will have a run on it, but not with high hope. It has a very early digital Y/C processing board in it with tons of SMD ASICs and discrete frame buffer SRAM ICs, and the corrosion is quite bad on that board also, some fine pitch SMD ICs are swimming in an electrolyte sea for who knows how many years now. And it was operated quite a lot after the caps started leaking, as the previous owner seen some issues with it gradually coming up, first the HiFi audio went out, then the tracking became unstable, and he stopped using it only when the servo completely gave up and the head drum started spinning at about 1/4 of the rated speed. I bought the VHS version of it for parts, the F785, because it was cheap and came with a remote, which the S895 was missing, but the F785 came with even worse corrosion, it has blown up caps in the PSU (at least the PSU was still OK in the S895 last time I seen it).

I would never recommend buying this old crap. What many do not understand is that these high end machines were not very reliable when they were new. Time has not been good to any of them. If you absolutely need a VHS find the most recent vintage machine you can find. Sure there will be more plastic in them but the reliability was much better due to greatly reduced part count. Fewer parts both mechanical and electrical means less to go wrong. Also the signal processing circuits on the later machines resulted in a better picture than any of the early machines could ever dream of delivering. Same goes for old cameras. For archiving find a digital 8 with analog playback capability. Early 8mm hi8 cameras were loaded with leaky caps. Later models they had all switched to tantalum and ceramic. I know this just ruffled ebay sellers feathers that make a fortune selling this old crap to the naive buyers to think older is better and therefore worth more. I just recently saw a guy with a 1947 Bakelite radio asking $300 saying it's rare. I sent him a message asking him if he would like to buy the two that I have for a hundred a piece and then he could mark them up to 300 and make a profit. I bought the two that I have for 15.00, for both.

@@12voltvids Good afternoon , guru! I apparently expressed myself inaccurately. Of course, you did not recommend purchasing this particular model. Of course it is not yours recomendations. But I myself assemble and repair magnetic sound recording devices (cassette decks, video recorders, DAT decks). It was enough for me to watch your video and want to find this device in my collection myself. Of course, after troubleshooting. Yes, time does not spare anyone, and magnetic recording devices suffer all the more from time. But. This month they brought me a very "young" Sony slv-se620. 1996. Weight 3 kilograms. All made of plastic, the tape tension stand is combined with the lever (also plastic) for opening the cassette cover. The stand broke off, the lower part of the plastic of the stand fell into the windings of the direct drive motor of the capstan, some of the windings shorted out to each other, the tape was crumpled (a very valuable record for the owner - his wedding ), the price of the device today is about 15 US dollars, the price of a direct drive for this device is about 100 US dollars. No point in repairing. My friend brought JVC HR-J627ms, it turned out that on the back panel the brand JVC HR-J727, the tape counter only works in ntsc mode, in other color systems the counter does not count at all, there are no (!!!) central cores in tulips for the audio signal input at all , this miracle can write sound only in ntsc at sp speed, in other modes the sound is not written at all. 1996. Friend bought this miracle for 250 US dollars. My test show a harmonic distortion coefficient of 0.1% on recording from a tape . Sound for an amateur. These are not my machines. I personally have a Panasonic NV fs900 and my test show that there are absolutely no differences between the signal applied to this device and the result on the tape. Harmonic distortion factor 0.009%. Perfect sound. And the tape drive mechanism of this device has an unlimited resource - it is all made of metal. 1986. And here is Victor 8000. Today, its harmonic distortion coefficient is 0.05% I will adjust, it will sing no worse than fs900. Sincerely, Alexander.

Large scale integration thats why. They put everything into a couple of chips. They made them much simpler and much more reliable. I would take a late model VCR any day over one from early 80s. Yes they are more "flimsy" as some put it but if you load them gently they generally are pretty reliable and with the reduced part count,both electrical and mechanical there are far fewer points of failure. They are no more repairable though as no parts are available regardless of the vintage. Plus advancement in signal processing with the advent of DSP means that a newer vintage machine produces a better picture then the older models could ever be expected to produce.
