Thanks Noel, it is indeed all in very nice condition cosmetically.

The small board when the motor sits needs replacing as the solder tracks are damaged.

The replacement motor I bought is not identical to the original, but tested OK with a 12v power supply.

The small nylon coupler on the motor completely split in half as well, and I have not been able to get hold of a replacement.

It's an ideal candidate for a repair for anyone who can get hold of these spares.

Anyone interested please feel free to email me.

Mark,

That is a really nice looking SLHF950. Have you considered trying to get a motor and gear from an old Sony VHS machine SLV815 or SLV777 models. I think they should adapt. I have used them for repairs on the SLS2000 model super betas.

The mechanisms are different but that drive gear is quite similar. It is a common problem that gear breaking but I take the gear off, plastic weld it across the crack with a soldering iron and use a cold chissel to score a rough surface or cut running along the motor shaft so that when you super glue the gear back on there is something for it to grip to.

regards Noel

I got a new motor from ebay and fitted it, but then had some problems with all the small wires going to the motor / board breaking off.

I have given up on the repair and I can't get hold of the plasic gear anyway.

I've now decided to sell the machine for spares and thought of your site.

Before the motor packed in and the gear split in half it was all working well.

I have put it back together best I can (minus the plastic gear).

The tray doesn't open now and the machine is of course unusable in its present state.

It's very nice cosmetically, as is the original remote and manual.

I am in London E4 area, please contact me if you know of anyone who might be interested.

Regards

Mark

Hi Gabriel. Thanks for your quick response. I wound the loading ring back manually using the pulley, then brought the carriage up with a slim forefinger on the worm gear, so I am now in unlaced condition. After posting, I noticed that the rod holding the two tiny metal gears was not quite parallel to the front panel - the carriage is skewed. Further investigation showed that the alignment holes in the two gears which these mesh with are about 15 degrees off alignment. So it's off with the front panel, realign the carriage and try again. I'll look out for the little gear you mention. Odd that it worked fine, and has not been forced, so I shall look carefully for anything broken. The service manual gives instructions for operating the loading system with the assembly out of the machine, so I'll try that before reassembly. I'll keep you updated. Keith.

Hi Keith,

I am not sure if I have taken the whole picture regarding your issue. It seems that the machine is unable to unlace? I have read you pulled the tape manually but I get the impression the machine is still in full laced position.

If this is the case, I would blame the small loading gear underneath the pulley and belt loading assembly. In the C9, it is a tiny white gear. It is easy to disassemble and worth checking for cracks.

I think I have a couple original good condition gears of that type at home but anyway you can try glueing it for a temporary fix or even try to get a similar gear from RC spare parts (AliExpress, eBay and so forth).

I hope to be helpful.

Greetings,

Gabriel

Further to my earlier post concerning skate motor for HF950, I have purchased this 6-12v motor from eBay https://www.ebay.co.uk/itm/MABUCHI-RC-280SA-20120-DC6V-12V-9V-11300RPM-High-Speed-Small-Mini-24mm-Motor-Toy/254549731156?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649

Hope it works, but I still need to try and get hold of the nylon joint part no. 3696-388-01 and rubber bushing X-3696-389-1

Hi.

Further to my previous post, clarification of symptoms: from a cold start, eject light is off, pressing it gives solid light and reel motor runs; then it starts to flash; pressing eject again gives solid light, then flash, but with no reel motor. Inserting a cassette produces no effect for a couple of seconds, then light flashes. There is no sign of activity from either loading motor in all of the above. When a tape was loaded, and unejectable, all other functions of the machine were normal.

Keith.

Hi.

I have 2 SLC9UB machines. One from new, with dead DC-DC and split plastic cogs, otherwise OK; the other I bought a couple of years ago with upgraded DC-DC and metal cogs. The latter worked fine until yesterday, when a tape wouldn't unlace and the eject light flashed. I wound the tape and cassette out via pulley, worm and occasional repowering to wind the tape into the cassette. I have the full service manual. I realise this is a complex system with switches, motors, microprocessor, mechanicals all potential culprits.

Please will someone suggest a logical order in which to fault-find. Unfortunately, the obvious first step of swapping the cassette compartment assembly between the two machines is a non-starter in terms of fixing the fault, as the older assembly is u/s, but I could put the 'newer' assembly in the older machine and get old faithful going again (without display). However I'd really rather fix the newer machine.

I was in the process of copying old tapes onto DVD RAM on my Panasonic ES-10 and thence into computer. This works really well because the ES-10 faithfully copies what it sees, noise, glitches and all, whilst all the USB video transfer gizmos stop recording or output a blank screen when they encounter noisy signals.

Thank you in advance for any help you can offer. (I have seen the post in the technical section concerning this fault, but need a place to start.)

Best wishes, Keith (Leicestershire, UK)

Hi, I am in the UK and looking for a part for my HF950.

It's the skate motor assembly M905.

Gear has split in half and motor has broken inside.

Perhaps somebody on here has a second hand or new spare they could sell me?

Thanks

Hi,

Does anyone have a copy of the SONY SLO1700 service manual?

I have a photocopy but I am missing information of the circuit layout for the SS27 servo board (Pg76)

If possible could someone email me a picture of that page or if possible all pages associated with SS27 servo board.

regards Noel

Hi Noel,

That's good to know you have already tested it.

Thanks for sharing!

Gabriel,

The superbeta performance is achieved by changing the electronic recording and playback parameters which were selectible in three modes to better utilized higher quality tapes. As far as I know the heads are the same.

The SLS2000 has different heads but the same three selections available which made the colour change when you played back a normally recorded tape.

By moving the signals up in frequency to utilise greater bandwidth, a slightly higher line resolution achieved.

I have repaired about 5 SLHF950s using the SLHF150 heads and they seemed to work fine.

Swapping the heads from HF100 /150 with the magnet removal trick works for regular Beta and HiFi, but is SuperBeta for the HF950 still guaranteed?

As far as I know (read at some online forum time ago), this doesn't work for VHS - SVHS because of the higher bandwidth needed.

It would be worth investigating.

Greetings,

Gabriel

Gary,

OK I will email you.

Yes the HF150 heads fit both an SLHF100 and a SLHF950.

For the SLHF100 you need to remove one of the magnets - you can see which one when you compare original to new.

For the SLHF950 the rewiring is tricky because the colour of the wires changes and there are fewer.

You lose the still picture 1/10 & 1/5 slow motion functions but 9 times scan and x2 work OK.

The really good thing is it returns the machine to work for all its other good features - syncro editing, APS search real time counter etc.

As for the front panel cover- I just checked and I don't have any spares left, I must have used the one I was thinking about on a recent repair.

regards Noel

I am delighted you can provide both items as the unit is in mint condition and is well worth repairing.Not sure of your email address.I am at [email protected]

Many thanks.

Gary.

PS am I right in what I am saying that the heads for the 150 fit the 100.

Many thanks again.

Hi.I was wondering if anyone has a new head disc for the Sony SL HF 100. I think the head disc for the 150 also fits by remoning the appropriate head switching magnet.Also looking for the front flap for the above model.Any help would be much appreciated.

Many thanks.

Gary.

For general information,

I managed to source quantities of at least 10 each of the ICP-Nxx series fast acting semi conductor fuses I mentioned in a post below, except for the lowest rated ICP-N5. (Two ICP-N5s are used in the SLHF950s)

regards Noel
