Lydia,

If you don't want Noel to fix the machine, I'll be happy to come and collect it.

Cheers, Roderick

I thought I'd posted this but then "lost" this chat page. Now I've found you again so ...

I'd be happy to sell or give away our beloved SL-HF950 that is not powering up (previous was working just great also tray is a bit loose)

I don't want it to go to the tip! Also quite a load of old tapes.

I'm in Sydney Australia

Steve,

The 5 Amp is what I use these days. The machines demand a 4 Amp surge current at times so 3Amp is not enough for reliable operation over time.

Noel, should I go with 3A or 5A rating? None I found are rated at 4A.

Thanks for info Noel. Love to have instructions on how to do this upgrade. I would use externally I think.

Steven,

Failure of the SLHF950 power supply is quite common after all these years. The design is basically a 240VAC to 12V DC (@4Amp) switch mode supply followed by a DC to DC switch mode which generates all the required voltages needed by the VCR.

The capacitors age and dry out losing capacity plus their ESR increases and the result is the failure of the first AC to DC convertor power transistors and other components.

Indeed capacitor aging effects other aspects of the VCRs operation as well but most can be rectified by adjustment or replacement.

Whilst these issues can sometimes be repaired my solution is to replace the first section with a modern and more efficient switch mode power supply connected the the second DC/DC section in the SLHF950.

See https://www.ebay.com.au/itm/AU-Power-Supply-Adapter-Transformer-AC240V-To-DC12V-2-3-5-6-8-10A-for-LED-Strip/162567927732?hash=item25d9cdb7b4:m:mJucG2iLZGn9TWRzhqLSWZA (they seem to be commonly used for LED strips)

You could use this external to the machine but if you mount it in the machine an earth wire must be added because the machine can float at half mains voltage due the the leakage generated by the mains EMC filters.

Hi! I am having an issue with my Sony SL-HF950ES. The deck is failing to power on. It is completely dead. Is there a fuse for the mains in this deck. I remove cover but see little that ressembles a replaceable fuse. Any advice would be great.

Martin I have purchased Rubber Renue and will have to test it on a friend's VHS VCR which chews tapes because of its pinch roller. I will tell the result here.

Update on the problem tape: I cleaned it - no more head clogs - I passed a microfiber cloth over the tape both sides using rewind and fast forward functions - I held the cloth bound to a slender rod held vertically - no apparent damage to the magnetic recording though it is starting to deteriorate with age (some blackframes) (28 years old +) - recorded in superbeta I now transferred contents (boxing matches) to digital - image is still sharp. I'm amazed how resilient the Betacord machine is (not the one I used to record - I lost that one) . Thanks to all the cleaning tips (external and dis-assembly , on this site.

The PALsite pinch roller page has been updated to include a YouTube video from Noel showing how a pinch roller can be rejuvenated.

Having manually done something similar to a number of pinch rollers, this certainly looks like a great approach!

@ William - Try hairbands from the dollar store for band pulleys if you have these kind of stores where you are - they come in all different sizes, have the right kind of stretch and will last, Worked for me for the small one for the cassette driver. Pure elastic bands also work but might have a more limited shelf life. . They sell packages of elastic bands of assorted sizes and thicknesses.

The hairband has a wrapping around the elastic which makes it more durable.

Hi all,

For your interest ---

I have recently converted tapes to digital from a Betacord Sanyo model 3900. One particular tape is a challenge. It caused the cassette driver to slow down and the cassette driver band broke. (The tape mangled and I ended up splicing it and repairing the splice.

I replaced the broken band , first with elastic bands which had a shelf life of about 6 hours .. then with a small hairband from the dollar store (Almost perfect size , I brushed plastic cement on it to give it some more tightness and friction . Works perfectly.

Back to the tape - I got it going - wind and rewind at speed not and played a few times but I can't get a clean digital transfer - often, problem is at certain sections - it keeps clogging the heads for some sections of the three hour recording. Testing shows the data is still there over these sections but it is as if the sections are randomly dirty I have to use tape cleaner cassette or play another clean tape to get the heads back reading. Time consuming and dangerous for the heads.

...

So, whats with this tape ? Is it dirty or does the clogging come from the tape itself degrading in some way and bits of it coming off?? I've attempted some kind of clean - running the tape at rewind brushing it over a microfibre cloth held vertically wrapped around a Q-tip - so far with uncertain results. I'm puzzled what the problem is which is my question. I'd like to experiment more but I'm taking a chance on messing up the cassette driving mechanism which I almost did several times.

Thanks.

Max

Glenn:

There is a set suitable for your 5150 currently on E-bay. They may be willing to ship to new Zealand.

Other than that a good used set should be fine.

They aren't all that common anymore (new set's that is).

Glad to be of help.

Sometimes the simpler things are all that's at fault.
