Sony SuperBeta SL-HF900 part 2. Super progress.

[@snap_oversteer]

What a machine, it's impressive that it was just the regulator and hall effect sensor considering how advanced it looks inside.

[@more.power.]

Thank you for the brilliant tutorial for the repair and the ordering of parts. Cheers

[@Petertronic]

Excellent and useful tips on the hall effect sensor replacement, great to see that worked and the regulator too. Machine starting to look very good indeed!

[@colourist.]

another really enjoyable video. coming from a lifetime of broadcast videotape and film myself this is so great to watch . keep up the great work!

A couple of years back, I took delivery of an SLHF950UB, the ultimate Betamax for the UK market. I'm following this series with interest in case I ever need to conduct any repairs on mine.

[@MrBetaByte]

The HF950 is quite different to the HF900 especially the power supply. No STK and it uses a switch mode power supply.

[@video99couk]

I would love to get my hands on an HF950!

[@richrootes]

Treat it with care! I sold mine almost exactly 20 years ago, I had had it since new and babied it - hope it’s still out there giving pleasure. Only problem I ever had with it was that it went through VU meters - I think I replaced them twice, oh and the linear audio/erase circuit needed fixing. I think I still have the service manual somewhere….

[@chloeleedow7250]

They used those STK ic's in sony amps in some of the 90s lbt series as power amps. What a beautiful old VRC 😍

[@video99couk]

I think the STK series chips used in amplifiers are different part numbers with different functions than this regulator circuit, but the construction was very similar.

[@joebutters4419]

Great info on the Hall Effect sensor. I now feel brave enough to tackle my SL-HF950. Thanks Colin!

[@TigerBoyRS]

Another cool VCR working again 💪 Great that you keep those old giants alive! Congrats. Cheers 🇵🇹

[@alphabeets]

I’m thinking that there was still a good amount of debris around the pins of the original Hall effect sensor. I wonder if cleaning around its leads more thoroughly would have fixed it. After all, the old sensor was kind of working. Just a thought.

[@jamesbrentnall2]

Same here I must have changed well over 50 hall devices never had one that worked by cleaning the glue off

[@dv_vid]

The picture quality, could it be the white clipping adjustment? Also, check the rotary transformer glue has not turned to mush as did the hall sensor.

[@peterkutas1176]

Conductive glue was huge problem way back...

[@zx8401ztv]

Well done, colin :-D, it's looking good, the hall effect device is a spot on replacement, Nice :-D At last a real stk regulator pack.😀 I bet your solar panals have charged the batterys up to the brim.

[@bjarneanthony7797]

Good work Colin if you need some video 8 tapes i have pleanty new Ones still not packet out.Anthony

[@Ragnar8504]

Are there any EU machines that share the same power supply? In that case the easiest thing to do might be to swap the transformer if the original only has a 100 V primary winding.

[@orihalcon8693]

I've seen a few comments about the voltage conversions for different machines you're working - why not just use autotransformers? You can hand select whatever output voltage you want that way. Main downside I see would be accidentally plugging in the wrong power source if you were instead wanting something more permanently attached to each machine.

Man, now THAT'S a remote! 3:51

I have a Sony SL HF360 Betamax VCR and which I brought from a Estate sale which it looks like it was in great condition but it does not feed the tape around the drum and then ejects leaving the tape sort of unraveled. I would like any suggestions that you could provide ... I have several Beta tapes to view then transfer to digital format ,, Thanks

[@video99couk]

It needs to be looked at by someone who is familiar with these machines. There are fragile parts in the mechanism and it's all too easy to break something and make it much worse.

[@frankowalker4662]

That is a much easier way to replace the hall sensor. 👍

[@stpworld]

i wish you were in USA i need my super beta fixed I have the one with tthe built in home theater

[@video99couk]

Try contacting 12voltvids, he's Sony trained and a real expert on these.

[@stpworld]

@@video99couk i have before and he did fix many of my items but this is to heavy to ship

[@stpworld]

@@video99couk There was an update to my situation I got some one in my area to fix it its 100% repaired now and I didn't have to ship it out. It needed a new loading belt and a new capacitor in the video output board. They also fixed my bang and olufsen headphones which failed on the cabled line in connection.

[@stpworld]

@@video99couk Oh i randomly have a brand new old stock sony betamax head how rare is that to have?

[@rodrigobelinchon2982]

that test tape !!! hahaha

[@video99couk]

I was hoping no-one would notice. It's just the only NTSC Beta-I tape I have.
