Sony Ps-8750 W0W!

I picked up my ps-8750 last week and boy is she a honey! I had to lube the return arm gears with lithium grease and replace the return arm belt. I used an ordinary rubber band, for the original was nothing more than a black rubber band. I flattened the platter mat in the oven and it seems it has enough oil still left in it! I polished the platter and brushed aluminum base with Noxon. I have yet to apply car wax to the top of the plinth. Killers looks aside, this table sounds amazing. It's the best table I've ever heard! Nay sayers for direct drive units would eat their words after hearing this superb table. I've heard details I've never heard before. This unit is sitting on a marble top table. Even on a table (on harwood floors) it refuses to pickup resonance. A wall mounted shelf is going to be its future home. There are still a few issues I have to sort out though. The tonearm is a Sony PUA-1600S. I had to guess at the anti-skate weight because I don't know what the lines represent for weight. Also there is a small slide weight on the front of the arm that I set in the middle. What is it for? I sent Yamaha B-2 a private message inquiring about dialing in the tone arm. Does anybody else know?

Well any who.. here's some photos !

88,

Be careful next time you clean the platter to not damage the brown-ish part inside it: it holds the magnetic imprint which the pickup under the platter reads to keep perfect speed up the 180g loads. Damaged imprint = erratic speed!

And welcome to the Sony club !
 
I wouldn't dream of touching the magnet! Thanks for the heads up though. Does anyone have access to an owners manual for this arm or table?..... (tumble weeds blowing)

Not the magnet. It is the rust looking stuff on the bottom and inside lip of the platter when it is removed. Is similar to the stuff imbedded in a magnetic tape. Soft and relatively easily damaged. Standard stuff on the better Sony TTs right to the end (when they stopped making good TTs).

Owner's manual. I've been looking for one for a couple of years with no luck. Mirko doesn't have one, either. I've seen a couple of other PS-8750 TTs go by, but not an owner's manual in sight. That includes asking at most of the usual sources for such things.

First, no one knows for sure what the indent gradations are. Isn't in the SM. So, am guessing it is in grams, with zero being all the way in. You should be able to telly by listening to see if one channel is louder than the other and adjust accordingly. The other weight is to help account for some of the effects of the TA being an 'S' design. I run mine in the middle. But, listening will determine where you think it sounds the best.

I scanned the page from the SM to send when I get your e-mail address. I don't have the rest of the SM scanned in as yet. There is precious little operational info in it, though. That is why the owner's manual would be so useful. The service manual is almost strictly service oriented.
 
Yamaha,

Thanks! That is very useful information. Have you tried to contact Sony for a manual? I know their website doesn't have one, but I think it's worth a try. I'm so impressed by this table overall. I sent my e-mail to you in a pm.

Oh, and Deli I haven't tried that album yet. Wise ass! You just wait.......
 
Haven't spoken directly to anyone at Sony. Let us know what you find out. TA page from the SM is on its way.

Also, I have been running the AT150Ti in the Sony and it sounds great.
 
88G,
It's galling when after years of being told that Direct-Drive is crap,one finds out that not only is DD not crap,but when done well it beats the pants off most belt drives.
I've got an Oracle Alexandria which I'll never use again(I bought it new,my only TT for 18 years).I now see the mainstream press as a division of the industry sales force,whose job is to move units off the shelves.Like politicians they'll tell you what you want to hear.I now like testimony from owners rather than the secret salesmen.
By all accounts the 8750 is a great DD.
Here's wishing you many years of listening pleasure from it.:thmbsp:
 
It was pretty gray looking, but noxon is a miracle worker. I recommend using it on a small spot first. the rag was black when I was finished.

One more additional note to this thread:

I contacted Sony today and they said they would do a search in their archives for the owner's manul. I'm keeping my fingers crossed.

That would be a wonderful find. Please keep us posted. If anyone has any other sources, the part number is 3-780-752-21 for the USA model and -11 for the European model.
 
Should be a great sounding turntable!
From Orion: 1977-82, $900.
I have the $400 1981-84 PS-X600 and think it is wonderful.
 
april '74 to early '78 in Japan, late '78 elsewhere.
sometimes I really wonder what Orion is :g

[edited the "1974" which I had forgotten to write - otherwise, it would've been the fastest appearance/vanishing of an audio component ever :g]
 
Congrats on the PS-8750

My PS-X500 will never leave, had it for 20+ years and not a thing has gone wrong. I can only imagine the level of quality of the PS-8750. The TOTL Japanese DD TTs are hard to beat and these are the ones that were exported to USA/Canada and Europe. The real TOTL beauties never were exported from Japan.
