..and finally some of my projects I an chewing on:I'm considering do build a Y /C to DUB & DUB to Y/C converter.So far I stumbled accross some very interesting things - first of all, after just plugging in one of my monitors FBAS INs into various holes of the DUB OUT socket of my 9850 I discovered that there appears to be transmit the combined (comp./FBAS) signal as well, - and another one, which my monitor sync'ed to , but appeared with a very moireé-like pattern (which looks like either a modulated FBAS - or something where the luminance FM-signal got filtered out.To both these signals my monitor could a) sync & b) resolve it in color..The other lines didn't cause (or output) anything.I expected one B&W Y-signal out, and something the monitor can't handle (i.e. the "C-signal" the subc. mod. C)

Despite of that - I checked my handy TV-technician cookbook to see, that the internal split-up & de/re-modulation, which is done in VTRs is actually done very simple.

Every home VTR splits up the FBAS to F & BAS, takes the luminance, and codes (modulates) the Y to FM, because elsehow it's very difficult to record static signals magnetically (like a white line).But that is of no interest to me, since only the "C-signal" is in the wrong format.Reading further on, the C-component gets modulated DOWN from 4.43MHz by some average FM-voodoo.Simply by confronting it with a 5.061 MHz oscillator, which generates a new C-carrier of 627kHz !Since umatics don't use any magical recording techniques, but simply higher frequencies & are better engineered - it should be possible to convert an FBAS OR Y/C to DUB as easily as described.BTW - *exactly* the same way the signal can be converted from DUB to an FBAS (/ or Y/C) - means: confronting (->mixing) the xxx khz signal with a (example) 5.061 MHz signal -> gives you a 4.434 MHz mod. C-Signal !

If I'm wrong, please correct me - elsehow I just need to worry about building a precise 5.xxx MHz oscillator circuit, and obtaining the exact frequencies of the umatic HB/SP/LB format - which I will right now on this page :)=)

Thanks for any hints-JanK

First of all thanks Frank - I thought the BVT-2k would be the best destiny - but now I'll look around for the one you've recommended - especially the weight of the 2k doesn't appear that healthy to me..

*Art Chudabala* - EXCUSE ME FOR THE HAIR-RAISING HAVOC I've posted before - I was refering to the PORTABLE VO-6800 - meanwhile you're talking about a stationery type VO-5800 (next time I should put my glasses on..).

Of course it's possible to get such converters, and you can control everything (such as jog,frame-stepping) you could ever dream of. There are a few manufacturers still selling such devices (the only one that I can recall, is making very rudimentary boxes which just allow FF,RW,STOP/PLAY/REC.. Another way is to look at some eBay auctions - or get it used/refurbed somewhere.Again - you could try to do something by yourself - I do have quite a bit of the P2-Protocol handy in case you'd need it. The only thing you'd need to get is a service manual which explains how to steer the specific functions (most of them are TTL, which you just need to tie either to ground, or to 5 Volts - these include all the buttons you're seeing on the front-panel of your 5800).The more specific controls are the jog-control - this is most likely sent serially over some pins as binary data - OR just as a frequency or PWM - signal.

When you've gathered that information, you could build a "small" protocol-converter-box. (In worst case by using an PC-486-mainboard & an appropriate (ISA or PCI) RS-422 card, and some ISA parallel-Interface-cards OR a special TTL-card with enough TTL-lines (the got to be as much as the 5800 needs).

In case you want to work that out - contact me - or post something here. (But I doubt that you want to continue after reading this posting :-))

Can anyone tell me how many hours the heads on a Sony V0-8800 3/4"U-Matic SP portable deck can deliver before the picture begins to degrade past the acceptable limits. Does the hours meter read the number of hours of use, or read from the top down i.e. the number of hours left on the heads? Thanks

As to Art Chudabala - in case the remote to RS-422 conversion -

you know that you won't be able to control more than the VO-5800 's front control would allow (Play/Record/Pause/FF/RW/Stop) ? + even it's possible that some manufacturer has made such a converter - I never heard of something like that. I do have a VO-8800, which has also a remote-port, but despite of the mentioned TTL-leveled& serially sent functions you couldn't control much.

My 8800 came with time-code, so I can record everything to an editor - or in your case you could record the signals (splitted) to FCP 2.0 - and *then* do the cutting totally inside FCP 2.0 .

P.S. if you would want to control the 5800 remotely via RS-422 that desperately , and have some soldering&programming skills - there's a way (but it will take some free-time).

As to Paul: the VO-8800's hour-meter displays the head-usage.I wouldn't bet on that, but you should see degradation after about 1K hours (that's where the meter is maxin' out anyway..). You read the meter from "0" to "10" and everything is to be x 100.

If I'm wrong - please correct me someone, since I got mine without the manual.I assume you're not happy with the picture-quality. In case you got it 'fresh' cleaning the heads does wonders - but not with conventional cleaning - I just let it record&play it two new tapes, and rewinded a couple of times - now the picture is fine.. + In case you're using an bogus power-supply (like I do) - try some other power-supplies, with better regulation or more amperes - I tried such - and the noise went away & the picture is way sharper.

Ok - nothing left but wishing nice holidays to everyone !-JanK

Hello, with reference to Eugenes BVU870p-do the VU lamps still light up? Depending on the design of the psu, it may have just gone into shutdown mode. The slugishness of the transport is due to the loading belt slipping but if the deck hasnt been used for ages, then the grease around the gearbox may have hardend causing more problems. The gearbox isnt easy to strip down. The board you shorted out is the DT board. I have service manuals and spare boards.

Hello, I have a VO-5800 and I was wondering if the remote connector in the back of the deck can be converted to a 9-pin serial to use for deck control via RS-422? What do I need to be able to have deck control and timecode for capturing to FCP 2!?HELP PLEASE!

I have a Sony BVU 870 that i have recently acquired.

We plugged it in at work and it appeared to do something (try to load) but everythign seemsed very sluggish.

this was after I opened the lid.

I closed the lid and noticed that all the meters went out and so i opened the lid to have a look and saw that the board above the transport had net been seated properly and i think that the reinforcement in the middle of the top of the machine has touched the power rails for that board.

Has anyone any suggestions aas to what has porbably been blown (it appears that the Transport controls do not respond).

All the fuses in the back seem OK and all the edit buttons flash and blink correctly.

Even better, if anyone has a service manual that could be e-mailed, I would be very happy.

many thanks

Eugene Mark Sully.

(PS> On the subject, does anyone know what the servo fault is on the Betamax HF100 where the head becomes unstable and then stops?).

Hello all: I work for an Audio Visual installation and design group in NYC as an automation programmer. We have installed a number of referbished VP-9000 decks in a multi-media conference room at the clients request. Currently we are controlling the decks via the front panel Remote connector _( by basically stripping the IR carrier to send a qausi RS-232 signal). This works fine except the client does not like the cable out the front. This unit also has the IF-132 card installed. short of using contact closures on the multi-pin connector _( the control frame does not have enough Relay / closures left)_ I was looking into the RX data in connection. Do any of you fine folks have any information, protocol manuals, or relevant expierence using this early form of Sony Transport control ? Any help would be greatly appreciated.

I recently aquired a VO-5630 machine for cheap. I m thinking about combining it with an edit machine and a JVC or Sony edit controller. Can I use the 5630 in this combination? Any opinions on the edit machine I should buy?

Thanks a lot.

VHS is a world standard and very common in the UK

What may be a problem is if you are in a country which uses the NTSC colour system (the U.S. etc). Though many uk home VCRs do offer NTSC playback.

"??????? What a load of ol' pony! :-)"Mm...whoops. Yeah, well, I was writing an article on digital audio reproduction and conversion at the same time - 3am - and that's what comes of writing without engaging the brain first...It's called Jeffrey Archer syndrome I believe...

Mark - what you have is a "C" format reel to reel 1" recorder.This works very similarly to the old reel to reel sound tape recorders except that a rotating head (usually only one) lays the video track and a separate magnetic static head lays the audio tracks - much the same as all VCR's. I used to own a pair of these made by IVC.

Need some help here if possible. Just got hold of a Sony reel-to-reel video recorder called a sonymatic. Is this any relation to the u-matic format? It uses a large stationary video head that the tape wraps round in a large U-shape. Don't work very well at the moment, but I'm working on it. Think it's from the 70's.

Well, for anybody that remembers my posts from this past Sept., I have a Wollensak VP-205, which as I just discovered is the same as a Sony VP-1000; as there is one on Ebay at the starting price of $1.00; it ends in 7 days if anyone wants a piece of nostalgia. In my case I can't see spending $32.00 shipping plus the cost of the deck for the power cord. Yeah, I'm still looking for a power cord for this Wollensak. Obviously I'm in no big hurry or I would've found something for it by now. The 2 places I thought would've had such a cord didn't. They both said call MCM Electronics. Maybe, if I don't trip over one around here. Oh, the Ebay for that VP-1000 is: 1304216738 . Later. Pepse.
