    I have the same BSW75. All capacitors in my power supply were defective. I also had the problem with the belt pull. The belt tension can easily be readjusted. Sony says that you need a special cassette, but there's an easier way.
    You attach a thread to the sensor lever for the tape pull, and at the other end you attach the weight that Sony specifies. Then you let the weight hang down on the outside of the device so that the desired tension is achieved on the thread. Then you call up the recorder's service menu and use a screwdriver to adjust the Hall sensor on the tape pull lever. The recorder's service menu supports you.

      This was the top model for Beta SP, I have three of them. It had a very high price tag, for the same money nowadays you can get all the equipment you need for a video production house. Yes they were made good but too pricey.

    The most common cause for this issue is defective or broken solder connections on one or both reel motors. This is a fairly typical problem in Sony Betacam decks, but the good news is that it is repairable.

      I suspect broken connections. Or a lose plug. It will get back on the bench at some point and there will be another video. Unlike a broken power bank or cheap VHS this one will get the attention it needs. It aparantly worked until it was removed from service. It got bumped around being moved so that may have knocked something lose.

    Hello, there is a switch near the tracking and video knobs and it is probably in the upper position, and all functions are remotely controlled. It should be in the middle position. Remote local. But I can't see it properly in your video. Try pulling the cards slightly from conectors and then push them back ,kind of contacts cleaning. Anyway, big fans of yours.

    Is it even possible at all to work on the slotted circuit boards on broadcast gear like this? I've got a BVP-330 camera that uses the same design with the boards being slotted into a mainboard like cards on a PC. The service manual always says to use the extender board for service but it's basically impossible to find them for sale nowadays. I need to check the voltages on the power board. I think it's capacitors. Should I just try replacing all of them and seeing what happens?

    Looks extremely similar inside to a JVC BR-S525 SVHS machine I’m working on which also has variable tracking and the slip ring contacts on top of the video head drum. It’s the only JVC I’m aware of that has “variable tracking” named as such. Pinch roller on mine was extremely cracked up and am waiting on a similar one to arrive that I hope will fit, but I suppose if the pinch roller or equivalent on yours is slipping, I could see that causing that sort of error- that or worn brakes of some type. Guessing you already checked that though haha

    • @12voltvids
      @12voltvids  9 หลายเดือนก่อน

      Not the same league for that matter not even the same sport. Svhs was consumer crap. sure they could dress it up a little and give it a little more resolution but it was still crap. Color only had about 30 lines of resolution in the chroma and even though you could have 400 lines resolution in the luminance the luminance is only good if you're watching a black and white movie. Add color and the picture is crap. Say those ratio was a joke. Yeah you can get broadcast if you shot something on svhs for the news and there was no other better source you could make it to air but you certainly couldn't do any type of serious production on it the signal quality was too poor to be even considered. Betacam on the other hand had full color bandwidth 120 lines each for the red and the blue and a full $340 lines of resolution for the luminance. signal to noise ratio was also substantially higher so it met the minimum requirements for broadcast and then some. That JVC deck might have been six or $7,000 when it was new which was a lot of money for an svhs deck but this beta cam deck when it was new was closer to 70,000. Again not the same league and for that matter not the same sport they're completely different machines this one here has direct drive motors for everything those little brake pads that you saw they're only engaged when there's no tape in the machine as soon as the tape drops down it actually disengages them because the tape is held under tension from the direct drive motors. I've never seen a machine that is as complex as this one. I have another beta-cam SP machine a cheap one that was only $14,000 when it was new. Dynamic tracking first appeared not only on these machines but Mitsubishi had it on their hsu-82 as well which had a separate pair of heads just for a trick playback and it had slip rings to drive them I have one of those machines and actually when I used it last worked pretty good I might drag it out again someday and give it a tune up because it was a pretty good machine however again it was svhs and thus limited to svhs's quality which was okay but it certainly was not broadcast

      @@12voltvids true true, wasn’t saying that VHS ever got close to betacam in terms of resolution or picture quality - these days main use for older machines is digitization and much of that is VHS stuff. I’m mainly curious if an older machine like that will produce an image that is better in any aspect compared to modern VHS decks where the technology had a lot more time to evolve and have probably much better signal to noise ratios as well as higher color depth DACs?

      Believe it or not i have gotten much better image quality from low end decks from the early 2000s. The technology was better. Dsp were being used to reduce color crosstalk and they just produced a better picture. EP got surprisingly close to SP quality on many of those late model VCR. Unfortunately LP did not improve at all and I'm many cases looked even worse, yet people used LP speed if their machine had it thinking it was better and it was compared to early ep, but not digitizing tapes ep looks better then lp recordings. HRS9911 is one hell of a machine for digitizing tapes with.

      The internal tbc really doesn't make a difference because my capture equipment has a full frame store tbc on the input so it really makes little difference. Sure if you're using a cheap capture card with no buffer then it could make a difference but any capture card worth being considered a capture card it really makes little if any difference

    • @12voltvids
      @12voltvids  9 หลายเดือนก่อน

      I doubt they sold many multi track 2" audio recorders. There are just not that many recording studios around. Three are more now because anyone can build one in a spare bedroom in there house back in the day of the big multitrack studios they're really weren't that many. Large cities might have had one or two and anybody that wanted to record went to those big studios. All the big bands all traveled to these big studios to use their equipment so they wouldn't sell that many of these 24 or 32 track $300,000 recorders back in the day however every small town pretty much has a television station and they all use betacam so there were tons of these machines sold for every TV station for their news operations for their on-air operations there was a shitload of them sold. Basic players would run around $14,000 that would be used for on-air playback of course there was automation players as well that would automatically load tapes and run commercials and everything fully automatic. But Sony sold tons of beta machines. So they may have lost the home video revolution to VHS but they won the professional market and that's where the money was. This video was just an evaluation because I wanted to see if it would work or not it hadn't been something minor like belts then I would have fixed it but it's more serious than that so I'll dig into it when I get a chance. no time frame it could be weeks it could be months but there will be a second part to this one once I get time

      @@12voltvids Yes, Back then everything was so specialized you didn't have a computer that you could look around on and say download Multi - track software as today. it was specifically manufactured and designed for a particular service or market I agree with You they had a captive market back then and not so much competition I bet a lot of the stations shelled out maybe $ 60.000 for three or four of the beta cams and before that as much or more on quad and 1" C equipment. I grew up in the tape error and we didn't have the computers phones and stuff of today so many of the young would get tape recorders and radios for Christmas I used to ask Mom and Dad for a new tape recorder almost every Christmas. i`am sure a lot of the stations back then had tape technicians to make adjustments to the tape and service and maintain I really like the quad TV tape used also 2" and the rotating head for the video and one or two stationary heads for the control track and audio quad never mad it completely out of the experimental stage when it was designed back in the 50`s they didn't have really any decent big servos so the machines had to be hooked up to a dry air compressor and they used the air to run the video head rotating and they used air guides to keep the tape in the correct tape path those I think had to be adjusted quite often and actually had warning lights and buzzers to alert the tape operator of a head clog or something out of adjustment. if it were like it were then now you would be buried in work and service because of your good work. tape had its problems and needed periodic maintenance cleaning and service but for some reason I never forgot it I still have such a hard time letting it go I got machines and stuff setting here for close to 30 years or a little more I know I need to be liquidating it but I just cant let it go yet ...... !!!!!

      It will be a work in progress for sure as I would like to get this one up and running. Probably the first thing is to check for any loose plugs. I guess if the transport is dirty and the tape is sticking that could cause excessive tension too. When I work on it in the future I will use a scrap oxide tape. Don't know when that will be.

    A few videos ago, you mentioned that a digital scope, unless insanely expensive, is worthless for RF envelope path alignment. So i bought a cheep old analog scope and indeed, it makes the job much better than my Hantek digital scope. What makes the RF envelop so difficult for a digital scope to handle? In fact, these digital scopes are totally unreliable:If I do not read a signal correctly I cannot really know if the problem is with the VCR or the scope itself. Why are they not manufacturing analog scopes anymore if the digital are so lousy replacement? I would expect a $500 digital scope to be reasonably good and this is not the case!
