Replacing the video head disc in a Sony SL-HF360 super Beta hi-fi circa 1987 with a (NEW from old stock) substitute 3 head disc. the original 2 head part DSR-84-A has long been out of production and next to impossible to find. however with some light improvising I found the 3 head DSR-27-A is a suitable replacement option as the pg magnets are the same. all that is required is to remove the A' wires as they will not be necessary as A' head will go unused. THIS VIDEO IS FOR DEMONSTRATION AND INFORMATION PURPOSES ONLY. DO NOT TRY THIS IF YOU ARE INEXPERIENCED IN THIS SKILL. THE VIDEO MAKER IS NOT RESPONSIBLE FOR DAMAGE TO YOUR EQUIPMENT OR BODILY INJURY DUE TO ATTEMPTING TO TRY THE PROCEDURE IN THIS VIDEO.

Love to see this, done this job as former Betamax technician from C20 to SLHF950 (AEP/Europe models). Recommended to replace the upperdrum (standard handeling for SonyNL) as well because it has changed a little bit in diameter. Without replacement upperdrum the new video heads can be decrease faster than normal. Recently i got Service Manuals from SL-HF100, SL-HF150 and the SL-HF950. (only AEP models).

That is true. if only we could remanufacture new upper drums as I have quite a large inventory of new old stock head discs. For units I sell refurbished with new heads I'll use a new old stock upper drum A-6760-138-A. but these are getting pretty hard to find, and costly when you do find them.

@dougfisher1813 4 месяца назад

I have three of this model. One works fine, one is for parts with a good drum/head assembly, which I need to transfer into another machine. The motor inside the drum is breaking into pieces as it runs. I don't yet know how to remove the whole drum assembly.

@michaelcrespo 8 месяцев назад

This is nice! I've always wondered how heads were made inside.

@MrBetaByte 2 года назад

Great video as ever and really good to see how to repurpose heads for a different machine. Really liked the way you used the threads in the disk to remove it too - they're good to 'crack' the bond of the head disk too if need be.

Unfortunately this video has come nearly 20 years too late for me. My last surviving Betamax VCR gave up the ghost at the start of this new millennium. By then they had invented DVD recorders and a few years later DVD recorders with built-in hard drives, so I just replaced it with those instead for recording movies and shows off live television broadcasts. I have recorded DVD discs going back to 2002 and they still play back perfectly.

Great job. I did this a week ago with mine Sony FP-60 Vidimagic(NTSC)Portable Projection System .For parts I used one sony sl-f1f(portable video recorder for SECAM).Sl-f1e - for PAL,sl-2000 for NTSC....Тhe disc with the video heads is the same.

@betamaxrebeloutpost8945 4 года назад

Good! keeping them going! yes those are the 1 pg magnet design. the head disc for ntsc sl2000 is A-6762-115-A. alternate head part is A-6762-077-A. yes, they work in many different units

I like your videos a lot. Are very hepfull. Today in 2021 a lot people have their betas vcr in good conditions. Can be usted this compatibility to other models? I have a sl hf950 and sanyo vtcm40 and id like to have couple of Heads for spare parts. Thanks

@betamaxrebeloutpost8945 3 года назад

Thanks! the heads for PAL HF950 are extremely rare/ extinct. and unlike the NTSC HF750, it is not possible to use a 2 head or 3 head replacement in the PAL HF950.

@betamaxrebeloutpost8945 3 года назад

@@josecarlosvilla4351 yes true that. so it's important to use these high end Betas as sparingly as possible. and you may be able to source heads from the HF150s, but i would double check that with the experts on the palsite.com

@JohnBoonBeanDutchman 3 года назад

Interesting to see, just wondering how or what made the old head broke, ore what be wrong with it

@betamaxrebeloutpost8945 3 года назад

as the machine is used, over time wear builds up on the head disc and the stationary upper drum. this causes poor picture quality to eventually no picture output at all. the head and upper drum will need to be replaced.

@zhaohaigaogu7821 2 месяца назад

If the head disk becomes wobbly after replacement, does it need to be adjusted?

@betamaxrebeloutpost8945 2 месяца назад

the disc is mounted flush to the spindle hub, there should be no excessive wobble. There is a slight inherent wobble on the rotary spindel in order for the head disc to acurately scan a track b track.

Well done, I am trying to fix my old SLHF900, need new head, pehaps I will try using a 3 head or 2 head, and I will post the results,

@betamaxrebeloutpost8945 5 лет назад

Thanks! Yes a 2 or 3 head install is possible. found a hf900 many years ago with a substitute 2 head and it was working fine. pause special effects will have a noise line. just be sure the pg magnets on your new sub match the ones on the original head

@jediurbanomxl 5 лет назад

I just read you message, hope this weekend have time to experiment with the slhf900 video head transplant, the magnets have any polarity or just the number of it need to match, I have some Superbetas to take parts including a new old stock nec superbeta, but was damage in the shipping and this machine record B1S, so tha will be the first video head to inspect.

@betamaxrebeloutpost8945 5 лет назад

@@jediurbanomxl the polarity is critical. you can't go by color (pink, yellow) i've seen them mixed. that's why I do a side by side comparison test of the pg magnets in the video. Best

Hello, I just replace the video Head from one of the SL-HF750 that i own with the 2 heads version from a SL-hf360 donor, the playback on B1s is very grainy and in B/W but the BII abd BIII is quite sharp, very good color and noisless until we use the variable speed, but for play back is a good player, if I not repaired this way it still wil be beutiful paperweight.

@betamaxrebeloutpost8945 4 года назад

That's great to hear! i am actually looking for a new head disc for HF750 before going with a 2 head option otherwise I too will have a very nice looking paper weight! LOL original sony pn: A-6762-255-A

@@betamaxrebeloutpost8945 a few weeks ago a came across a website that had it in stock, but for more than 400 dlls, i was surfing more and reading for more than 3 hours on the net, will try to trace the web side, also with some information from Mrbetamax, I will try to make any kind of mod to use just 2 video heads to use the B1s, like the Nec model (plays and rec with only 2regular heads) and the slhf900 (the 4 heads are used only for special effects)

@betamaxrebeloutpost8945 4 года назад

@@jediurbanomxl yes encompass (partstore.com) is the middle man to all of Sony's old parts stock inventory . they still have a lot but not for cheap Lol! last checked they had the entire drum assembly unit for the EDV-9000! NEC 4 head design is much different than Sony 4 head. the NEC 4 heads are spaced 90 degrees apart, whereas Sony the special effects heads are integrated into A and B heads.
