Also there was "BTS" which were re branded Sony Beta SP Portable decks and I think rack mounted units as well. Everything inside said "SONY" on it.

I've repaired a bunch of EVO-9850's (still own one with a mystery problem with one of the heads). The construction is quite different but the look and feel and the sounds are all very familiar haha. I love the modularity and serviceability of these industrial units. 2 screws for the lid, 4 screws for a complete extraction of the tape transport assembly (in case of the 9850 at least). 5 minute job to swap transports. The 9850 always needs a complete recapping on the main board (which is very easy to get to.. swings out from beneath, while still connected). There are some specific capacitors which are responsible for spinning up the drum and they're the usual culprits.. I replace those with X7R ceramics but quadruple the capacitance value due to the capacitance/frequency non-linearity of X7R's, and that specific circuit being sensitive to that. I never replace electrolytics with electrolytics. I use either solid tantalums or ceramics. Permanent solutions are best. ;) Another favorite of mine is the SVO-5800 for VHS. It's possible to remove literally all the casing and panels around the entire unit, exposing everything there is, while having it fully operational. Consumer units always had their wiring hell with limited modularity and access difficulty. Cassette decks like the Teac Z-7000 come to mind. All the budget went towards features and external appearance.. and internals were the typical wiring hell. Not my idea of an enjoyable repair. Thank you for making these videos, the world will appreciate them more as all these things become unobtanium relics. :)

I'm currently working on an EVO-9850P which is suffering from some leaking capacitors on a few of the boards. Luckily the damage appears to be quite limited thus far. You mentioned a few capacitors related to the drum motor which go bad, you do by any chance remember which ones those were? I assume they are located near the drum motor driver (IC801)?

Love all that great big deck for a little tiny cassette, lol. 8-Bit Guy uses an interesting method for brightening yellowed plastics. He uses professional strength salon style hair bleaching solution, your oldest could recommend some shops for it, lol. Just put it all together in a big clear bag and let it sit outside on a sunny da-ohhhh, right, UK. Ha ha. Maybe use a UV light inside then hose it off afterwards, lol.

Sony owes a debt of gratitude to Hitachi Semiconductor (now Renasis) for making the VTR Recording Signal Processing Integrated Circuit.

Fascinating! I wish I had the time, patience, nous and experience to even _attempt_ this level of repair. FWIW, after moving from using Umatic at work, to Beta at home and finally to DVD + PVR, I really wish that Video8/Hi8/D8 had lasted *much* longer, as they were my favourite format for versatility and quality. Better than Beta & superior to VHS; it was the compact cassette of video.

@@video99couk I didn't really embrace 8mm until I bought my first videocamera in 2001, which was D8 format. It also accepted Video8 and Hi8 tapes, preferably for playback. I was very impressed with the video quality, especially for the time. That machine made me pine for 8mm format across ALL devices. It would have saved us all buckets of money!

@@rahb1 D8 camcorders could only record in D8, not analogue. Most (but not quite all) D8 camcorders also have analogue playback capability, I use a fleet of about 10 of them for that purpose. I was a great fan of 8mm and bought my first EV-S9000E around 1995. It was not only used for editing, but also as my domestic video recorder. However the quality of that particular machine, was not as good as my best SVHS. It should have been at least as good as SVHS, but the EV-S9000E had a bit of an quirk recording certain images including captions.

The form factor and front panel layout is very similar to the Sony pro SVHS range like the SVP9020 which even has component out. Must be the only range of SVHS machines that did, although annoyingly not working on mine.

Might it have been an option that's not installed? There was apparently an MII machine which could play SVHS to Component and also some D9 players.

When Sony released Hi-8 it intended it as an originating format for Umatic SP. In the EVO-9800 booklet the VO-9850 Umatic SP machine is listed as an optional accessory :-)) You can see the complete package in 1996 "Trilogy" at about 8:30 mark: kzread.info/dash/bejne/f4aDp8aEncSdXZM.html AFAIK, "Dub Out" carries the same signal as S-Video, which is Y/C, just different pin-out. I guess, Sony did not want users to dub the final result off Umatic SP to Hi-8, I am not sure why. Was Sony afraid that people would make tons of illegal Hi-8 copies?

Umatic Dub has the same function as S-Video but does so in a different way using different frequencies and is incompatible beyond just the connector.

I still have mine. it is great. Hold on to these players.

9:05 I know I'm extremely late with this comment, but I believe that weird "MONITOR" connector offers either RGB or component video output when used with a right cable.

I understand that it's Composite only, and mono audio too. A very old connector type.

Colin, Hitachi rebadged a lot of Sony Hi-8 semipro gear like the CCD-V5000 and the EVW-300, they probably also rebadged the RM-450 edit controller. I have even seen the EVW-300 with a Toshiba badge.

I own a Hitachi portable c-format machine ! But Hitachi are probably better known for making JCBs than VTRs !

Hi Colin, I have a Sony VP-9600 NTSC U-Matic that I use for video transfer. Machine is working great but, I have a low saturation of colors or chroma on the output. Brightness is fine, image quality also. Do you know how it would be possible to adjust this ?

it is juste a rebadging , I used to work on betacam SP with AMPEX, BTS, Thompson logos , 100% Sony made and sold a little bit cheaper

I have a Sony Evo-9800P that I used to convert my hi-8 tapes to digital. I'm not gonna use it anymore so I would like to sell it but I don't know where to find a buyer or how much money it's worth. Could you give me some advice? Thank you.

I could be tempted myself, depending on price. Or let eBay find its own value. Note though that this model does not support normal FM stereo sound playback. Apart from PCM audio, it's mono, which limits usefulness.

I noticed in the outro that you have a tape oven for Umatic tapes. Please can you do a video on this process please.

@video99couk

3 жыл бұрын

Yes, must do that, a few people have asked. The oven is used for many tape formats actually.

I'm wondering if the problems you're having with balanced to unbalanced cables is that they're wired for an electronically balanced output, ie. ground to pin 1 and signal to pin 2 (hot). If the machine you're working on is transformer balanced then this type of cable won't work, as one side of the transformer will be o/c, giving a low output with noise. For transformer balancing, pin 3 of the XLR has to be referenced to ground by linking it to pin 1. This type of cable shouldn't be used with an electronically balanced output, otherwise the output amplifier stage could be fried.

@video99couk

The problem was weirder than that. When I had the balanced to unbalanced cable installed, there was a faint mains frequency buzz on top of the audio. When I switched to a pure unbalanced route, there was no such buzz. But I take on board what you have reminded me of there, I was aware of there being two types of balanced connection but hadn't remembered the detail.

I have a U-matic tape that shows the counter running up to 1 hour in 40 mins real time, the video is playing faster than normal with bad audio. Is it degradation of the reference signal?

If you have proven that the machine is OK with another tape, it could be a defective recording. Is there any possibility that you are trying to play an NTSC tape on a PAL machine or vice versa?

Greetings Colin, as you say, what the heck were Hitachi thinking ? (one may only imagine that they wanted a complete Hi8 edit package as they no doubt made cameras and camcorders, were awash with their own monitors and TV`s but perhaps the cost of tooling up for the number of Hi 8 machines they would sell was not a logical move, so just badge engineered a Sony, the Sony itself was a strange hybrid half one format and half another, no-wonder there was a strange selection and omission of inputs and outputs. Very interesting Colin, thank you. regards Simon.
