U-matic Video

P.S. I suspect that something is timing out. I have discovered that if I switch the mains switch on the VCR on and off rapidly when the small tape loop has formed, the threading ring motor comes on for brief instants to inch the threading ring round step by step until I can get the tape loop big enough for the fast forward and reverse to work. However, the ring motor will not come on to drive te ring round to the play position. I think there must be a timing-out problem.
Also, I have found a curious fuse-like component (glass with metal caps at each end and 6mm diam by 30 mm long) fitted like a fuse between a couple of clips on a small circuit board near the threading-ring drive motor. The glass is thick and contains a thin (about 1mm diam) column of mercury. Along side the mercury column is a scale marked in divisions 1 to 10. The column of mercury in it is not continuous; it has an empty gap in it about 1 mm long near the 1 division on the scale. Can anyone please tell me what this component does and whether the murcury column should have a break in it?
A column of mercury is placed in a thin cylindrical tube with a gap (bubble) in the fluid, the "fuse" tube in placed in parallel with a voltage (current draw), usually placed in line after the main power switch or in your case of a VCR, maybe placed on a motor voltage input. As the voltage is applied to the Elasped Time Readout, the voltage potential SLOWLY, SLOWLY, causes the the bubble in the column of mercury to move. Each line on the glass tube represents either 100 (or maybe 1000) hours.
When the bubble reaches the end of the tube, you simply swap the "fuse" around so that the bubble goes backward (it is polarity sensitive). Usually they would mount the readout in a standard old fashion open fuseholder so that the device could be reused.
These devices have been around for decades, proabably since the 1950's. They were usually used in lab or industrial equipment, but for a vcr, they were a fool-proof, simple way of indicating the amount of time that a piece of equipment had been used. (no curcuitry need, permanent static memory, no real moving parts, practically indestructable if not broken, etc.)
Hello all- I hope you will forgive some very basic questions from a newbie. I work in a University archives and we have a number of 3/4 inch tapes. While the eventual plan is to transfer material of interest- first we need to figure WHAT is of interest. I just unearthed a Sony VO-2610 and decided to see if it would power up. It does!
But really, if you are planning to transfer some of your tapes you probably should be looking at a better machine. The VO-2610 is almost 40 years old and very basic. For startes it is only 'low-band' and some of your tapes may be 'hi-band' or 'SP', which won't play well on your 2610. BTW, all the tapes look the same, it is just a different way of recording the footage onto the tape.You would be much better off trying to find a decent VO-98** which will play all formats. They regularly show up on Ebay for a $ 200 - $300. Anything more is a rip-off!Best of luck
Hi All, I 'm trying to back up some old videos and have been loaned a Sony VO9600. It was working fine until today, with a tape loaded inside which was running fine whilst running a test recording/copy onto a DV deck, after stopping the machine and then wanting to start again all the front panel transport control buttons won't work, the tape won't eject, although the standby light is lit. Can anyone give any advice on what to do and where to go from here. Is it possible to manually eject the tape? I have opened it up and had a look inside, but can't see anything obvious... many thanks for any information.
Confusingly, if the 'Standby' light is on it is not ready. What is indicates is that the threading cycle hasn't completed.Try if you can, carefully, to turn the threading ring a little further clockwise. With a bit of luck that should engage the switch and put the machine back in action.
I have for disposal an Ampex CVR 75 Betacam SP machine S/N 52315.I've also advertised this machine on the Betacam chat page. This machine is fully functional, free, and up for grabs, without dents, digs. scrapes, or gouges This is a golden opportunity to delve/venture or whatever, into the weird and wonderful world of Betacam SP. This machine will interface with Sony Umatic machines. It comes with a Maintenance Manual, User Manual etc. It is available for collection ONLY anytime from West Yorkshire. More details from [email protected] or call 01274 864826
Hello,I am looking for service manuals of umatics BVU-200P and VO-2950. I offer complet service manuals of BVU-850, BVP-360, BVH-2000PS or BVT-2000P for change. My manuals are in JPG format, shooted with very good digital camera. Please write to me at [email protected]
hey guys! i have a question concerning some u-matic devices. why do some (like the sony vo-9600 and the sony vp-9000 ) have both an rf (off tape) and an rf out connector? what is the difference between those connectors? i have read that the rf (off tape) connector is used for connecting an external tbc and the rf out connector is used for connecting a monitor or tv. but why is there an extra connector labelled tv then? i would be very happy if anyone could help me and explain what these connectors are used for (and what kind of signals are transported through them)
RF off tape is used for DOC (Drop Out Compensation) in a TBC (Time Base Corrector). A RF out is an output you can connect to the aerial input on your television. It would also show a channel number because you will have to tune your television to a specific channel. You would rarely find that connector on a professional machine for obvious reasons.Finally the 'TV' connector, usually a greenish 8-pin connector, was a left over from early video recorder connections. The connector provides both inputs and outputs and allowed a videorecorder to be connected to a specially adapted TV so that you could record 'off air' television. Early model videorecorders didn't have build-in tuners. The connectors stuck around for a while because they were a convenient way to connect a VCR to a monitor, connecting both video and audio signals with one cable.
Hi All, I'm in the market for 2 U-Matic Vtr players, must be PAL output, High Band with a TBC(time base correcor). Please does anybody have any ideas Where I can get purchase any in good condition. Please need is URGENT!!!
Janelle,Your best bet would be a Sony VO-9800 or 9850. Those machines play all varieties of U-Matic (low band, high band, SP). The tape could have been used to record in any of these formats.Are there any markings on the tape to indicate if it is PAL, NTSC or SECAM? Taht could be the next problem. But if you know that the tape was recorded locally, changes are that a machine you buy locally will work with the tape.
Hi. I have a SONY U-Matic Video Cassette Recorder Model V0-5630, a SONY 27" TV Model CVM-2711PS and a SONY Video Camera from the same era along with 100 or so U-Matic Cassettes. These items have been in storage for the past 15 years or so. I am in Gosford (Sydney) NSW Australia. If a collector in the area is interested in picking this kit up for free please let me know.
Regarding 'Error 20'. The manual tells me this is a System Error and that there will be a suberror shown on the monitor lower right corner.If you can post the suberror code I may be able to give more information.
I don't know if asking at the right place but, i'm after parts for my VO-2860p in particularly a pinch roller assembly i presume this is what i need? advice is appreciated. As well as causing crease patterns on the tapes i seems to be having issues with recording function. as pretty floorless picture comes and goes however when paused the picture is back until it's released :/

Can someone help me find the avaliability of sensor bulb, this is a stanley 23Volts, 3Watts. I've just brought an 5850-vo brillant machine but if i cannot resolve issues with the 2860p it can go for spares or repairs very soon.
Hey Everyone I have alot of u-matic machines I need to get rid of....Was wondering if anyone is interested in buying these machines?? To name a few here are some model #'s....VP 7020 I have a few of these....VP 5000 I have a few of these as well....SLO 323 have a couple.....I also have Wegener Communications Mainframe new in a box....I have alot of machines in this broadcasting era...If anyone is interested shoot me a offer....Would like to get rid of everything!!
I have a Sony U-Matic Cassette Player VO 5800 PS.Help! Any advice welcome!I obtained it around 1983, but it has had only about 200 hours use. It worked fine until about a year ago. Now when I insert a cassette, only an inadequately small loop is drawn out. (I've tried several cassettes, including a new unused one).
When the fast forward or rewind buttons are pressed, the mechanism clicks and the head drum revolves, but the forward or re-winding do not run.On 'Search' it makes the usual rattling/tinkling sound briefly when the knob is turned to either side, but then the sound stops. When I change the direction of search buttons the spinning flywheel changes its direction of spin.
If I switch the mains switch on the VCR on and off rapidly when the inadequately small tape loop has formed, the threading ring motor comes on for brief instants to inch the threading ring round step by step until I can get the tape loop big enough for the forward and reverse to work. But the ring motor will not come on to drive the ring round to the play position. The threading process stops far short of completion.
