Pat,

Thanks for taking time to reply.

I will have to ask around about either a low band machine, a tape known to be in colour and if anyone can recall if the tape I have should be black & white. There is a fair chance the camera available was only B&W.If the tape was low band B&W would the playback be any better on a low band machine than the high band JVC?

Also just been told about a few ( I will know how many soon) reels of 1" tape!!Hence would like to know about getting that transferred at a sensible price.

I found scan of the JVC video products brochure from I guess mid-1980's soon after PR-8800E introduced but that does not state either way. It just gives the recording format as ' High Band U-standard '. There is not a comma between indicating both modes. Otherwise stiil found nothing on the 'net.

Actually I have here two PR-8800E's and a RM-86U Edit controller with cables. Both machines load tape and output audio but only one gives a video signal output. Actually initially neither played nor registered a signal on the tracking meter but after about 3 minutes the picture gradually appeared on one. I've left tape running in the other for over 10 minutes but no picture nor signal on the tracking meter. I've had a look to see video head is spinning and checked heads clean with alcohol and proper head cleaning swab.

Is there anything obvious to look at?Ultimately as long as one works that is all I need. I am told the full system worked 3 years ago and just been in storage until now.

Also while I have machines I can possibly help anyone who needs tapes transferred to DVD-R for return postage costs and a negotiable amount for my time. This would need to be arranged promptly as while no great rush to return the machines I don't want the machines sat on my lounge floor for too long!!

David.

From what I remember yes. The control track is there anyway as it's used to control the Video head timing.I think there was a mod to allow the 5030s to work as an edit source deck. Think it was somthing to do with allowing the capstan to be controlled during editing.I think if it's a standard 5030 it won't work as a source machine.

Thank you for response. So I understand, that the machine with mechanical counter (as VO-5030 is) will still support the control track counter signal, and the editing controler can use that signal and show the counter on its display ?

Hi the VP 5030 is a play only machine. It can sort of be used as an edit source player but it's not ideal. It only has parallel control so search will be a problem.I'd go with a Sony RM440 and VO5800 source and VO5850 as edit recorder.Lowband umatic doesn't have timecode at all. It is possible to modifiy the machines but the parallel controller won't support that. This doesn't stop you editing. You just use the control track. Not frame acurate but it did the job for many years.Basically if your umatic has a mechnical counter it's not ideal for editing.Series 5 edit suite as above is best for control track editing. Series 9 is better and does have timecode (on highband) and serial deck control.

Hello U-Matic users !I'd like to get into U-Matic, But there is not too much information available. I'm interested in a limple linear editing system (yes, that's true ;-)). I'd like to ask fwe questions:

1. Is VP-5030 edit capabe ? I mean is there any way to control it from an edit controler ?2. What units can be controlled with RM-430CE ? It uses Parallel interface I suppose.3. What is the story with timecode on U-Matic ? I've heared about EBU timecode which is as I assume written on the invisible part of the picture like VITC not on the control track, so I think the tape mut be copied in order to have timecode on it ? Is it required to have the timecode in order to do assembly editing or the editing controler can use couter to find scenes ? And if so what about machines with mechanical counters ?

Thank you in advance for help, hoping I'll soon become another happy U-Matic user.Maciek

Been a while since I worked on one of those.Not all highband machiens could play lowband from what I remember. So it could just be it's a lowband tape and the JVC can't play it back. Can you find somebody nearby who can check the tape on a known good lowband play back machine?

I have been lent a JVC PR-8800E High Band VTR with the aim of transferring some tapes to DVD. The tape first tape I have been asked to copy was recorded 1979 so I assume low band. The playback is black and white. One possibility is the camera was only black and white.The other is compatability.Does anyone know if this JVC will play colour low band tapes correctly?So far I have found nothing relevant about JVC machines on the 'net via Google.

Thanks, Pat, for your hint on the power switch. I'll try to inspect it and see if it shows signs of arcing.

Most likely is a burnt out power switch. it's a common problem.They arc inside (that's the noice you hear) and go open circuit.

Don't mess with the mains if your not competent. But if you are you can test by shorting the switch out across the two poles.

When you get the switch out you can normally tell if thats the issue as it will show signs of over heating. You can even open the switch and do a temp repair but a new switch would be needed as it will go again.

Hello,

I acquired a VP-7000 playback deck a couple of years ago, and it worked fine until recently. Now it doesn't power up. I've found three fuses on a power supply circuit board and a fourth fuse (20 Amp I think) which I assume is the main fuse. All check out for continuity.

When switching on, there is a slight high-pitched sound, like a discharge perhaps. Trying again immediately there is no sound.

I have only very limited experience with electronics, wouldn't dream of messing with this if it were possible to find a competent repair person locally, but I wonder if anyone has a line on service manuals or other hints. I'm guessing something like a bad capacitor might be a possible cause, and perhaps even the whole power supply assembly could be swapped with one from a cannibalized unit.

Thanks in advance for any hints.

(Remove underscores in my e-mail address to reply directly. Thanks!)

The high band mod was basically a bodge. It modified the colour circuit to shift the freqency to the higher highband one. But it didn't make any changes to the luminance circuits. High band has a higher luminance deviation so higher bandwidth circuits are needed. The best the mods allowed was slightly better than lowband quality from a highband tape. And often they needed tweaking to get some highband tapes not to give black tearing.I fitted a few but it was a while ago.

Re the secam it's a whole different colour process as it's FM not AM so not sure how easy that would be.

I have not mentioned in my preceding message thet I want to modify a VO-5030 to VO-5030H. This VTR is PAL/SECAM/NTSC 4.43. The other VTR, the BVU-950P is stritcly PAL and I don't intend to make any mod.

There used to be a mod for VO-5030 and VO-5630 to enable them to play back high band in color. These VTRs had then a "H" suffix and an existing front panel switch was modified (I think it was the "Timer" switch). Does anyone have a clue how to make this mod? I have a BVU-950P but I have to copy BVU SECAM tapes. Thanks for any help.

Yes the idler flops from reel to reel.I'll check at work I think I may have some umatic spare I'm just about to dump.Maybe a reel motor in there!Certainly sure I have a reel idler. But like I say they rarely go wrong. i used to change tham in a service as routine but I'm sure they are quite tough.

Is the reel idler the white wheel and tyre sat between the spools (as you would expect)? The reason I ask is that some machines have two idlers. I actually flipped this tyre inside out and it didn't help, implying that the problem lies elsewhere. Bother, I probably need a replacement reel motor then. Now I wonder where I could get one of those?

The other possibility I suppose is the belt, I've not looked on the underside of the deck yet. But as you say, if this was slack it would be expected to part company.

Regards,

Colin

Just read the article about the manual removal. The wires don't need to be cut they are actually on a plug and just unplugs.Also if you can access the bottom of the chassis (by removing the bottom of the machine) you can manually turn the reel idler pully as you wind the loading gearbox on the other side. You will then have the tape wound in the housing before you eject.

Re reel problems:Just discovered this website. A real blast of the past. In the many years as a service engineer I overhauled more than 1000 various umatics, Particularly series 5 and 9.

On the slow reel problem. There are a couple of things to check.Most likely is the actual reel moter going low torque. The reel idler does wear but rarely causes a problem (you can test it by giving it a good clean with surgical spirt and seeing if it improves). The reel belt can slip but normally snaps. My money would be on the motor.

Lastly please oh please don't cut the tape it's completely possible to extract a tape with no damage manually.

Hooray. I did it !!!

Here is the article on how to: http://richardhess.com/notes/2006/03/13/u-matic-34-cassette-removal-procedure-when-normal-ejection-is-not-possible-%E2%80%94-guest-article/

I did cut the tape and it gave me another Error No. 20. Then I turned the bloody machine off and just turned the gearbox pulley ( as per article) manually clockwise until it stopped. Then I turned the unit on and presto, it ejected the tape. I had to cut the tape, but this avoided me on going the route of disconnect the wires, taking the tape compartment out etc.Hope it will help others. Good luck.

I have similar problem. My U-matic VO9850P made funny sounds and displayed Error 02 periodically when the tapes were very old and sticky and the machine had trouble winding them. Now I got a real bad one and it got stuck in the machine completely. So any idea how to eject the tape? I guess if I cut the tape inside the machine it won't do any good?

Poor rewind on VO-9800P:

My machine has slow rewind, sometimes stopping with Error-02. Is the rewind/ff idler the one which sits between the spools on the top side of the deck (with a small Allen screw holding it in place)? Or is it on the underside of the deck? Replacement idler or tyre source in UK?

Picture search still working fine.

Thanks for any help,
