SONY PS-8750 on eBay
- Thread starter friedmonky
- Start date
Thanks for your best wishes. May the Fedex 'gods' :ntwrthy: smile upon this shipment. 
I've said three chants and am burning several candles for the next few days. Will be hibernating until the boxes arrive. The suspense is getting to me.
Well.....not really. But would be nice to have everything work out.

PS-8750 arrived in good physical shape (nothing broken)!! 
Did get everything unpacked and put together. Did my first listen with the installed Sony cartridge with the DJ stylus (DJ - wonder what this table's former life involved?). Any way, all went together well and listened on my 'trial' system (STR-V4 & $15 speakers). Was in a great rush as was Valentine's day and hadn't treated the wife to dinner, yet. Didn't have time to run the gound wire. Results of 2-minute trial are:
- doesn't work in auto mode.
- no dampening on the lift mechanism. Seems to be the standrd for older Japanese TTs. Will dab the silicon dampening fluid into place and think it will be fine.
- has an electronic 'click' that goes through the signal. am guessing that it has a bad cap somewhere.
- spins up to speed and locks in quickly, so drive control seems fine.
- dirty, so needs a good cleaning.
- finger lift is missing from the headshell, but I have a spare from a SME 309 headshell that should work just fine.
More once I get the chance to actually give it some time. I'll post a couple of pic's, as well.
Thanks, again, Jeff. All arrived in good shape. :thmbsp:

Whew ..... now I can breathe easier. I knew the trouble you went to in order to get this to you ok. I was just hoping I didn't screw something up.
I hope it cleans up and shines like you want it to.
Glad to help an AKer out.

Congrats Glenn ! :thmbsp:
I think the click noise and the missing auto return/reject have a common cause !
I had the same problem on my PS-8750 and it was a trivial mechanical problem.
The problem may also cause a slight fluctuation in platter speed, which can be heard as a slight wow and flutter and a hum like vibration of the plinth ...
I look if I can draw a scetch for you...

Again, thanks to all for your thoughts.
Mirko - Yes, please sketch for me. I did notice on first run that the speed would not lock-in and there was a large amount of wow & flutter. But that went away and locked right in. You can either post here for all or send via e-mail.
Here are the pic's I promised. Will start the clean & polish process tonight. My clever names for each pic disappeared with the posting. They are:
Arrival!!
Its Open!!
Outta da box!!
All's Well!!
Jon S - Do you still have that parts unit that UPS provided? If not, do you know if the owner still has? I might like to have for the useful pieces. Thanks.

We pay top dollar for that white lawn (unfortunately, in the way of heating bills) each and every winter. Were it in my power, I would send you all I get each year. And am sure many other northern members would, too.
Nothing to do but sit in and listen to some good tunes or head to the range or some other festivity. Gotta keep that boredom from settling in. Have to admit, every winter is worse than the last. Need my light and warmth (and not the artifical varity).

Glenn here is my first try to explain it (in german English):
The tonearm mechanics is driven by an independent motor, wich is connected to it by a small belt.
(A really good turntable has a belt drive for the arm and direct drive for the platter .... )
On my TT this belt has lost some part of it´s strain and was not able to transmit the torque, which is necessary to start arm movement.
The result was, that the motor ran all the time, but the belt slipped over about every second (click noise) and the platter brake electronics was activated all the time (hum of the plinth), even when the platter was spinning (additional wow and flutter, because of fight motor electronics against brake electronics).
When I cleaned the belt with some alcohol and increased the strain of it, the arm motor was able to execute the complete mechanical program to the end, the arm went back home and after that the motor stopped and the hum disappeared some seconds later ...
I also had to replace a dry capacitor in the strobe light generator. I would recommend to do that with your TT too, because the strobe light generator has a feedback to the XTAL-lock .. !
Quite a complicated beast, which doesn´t sound very good if anything goes wrong inside.
After these and some other repairs, the PS-8750 suddenly was extremely silent and all the click, hum and wow + flutter were gone ....

Mirko - thank you. I'll check everything out this weekend. Sure does help to have someone on the thread who has been through all this before. :thmbsp:
BTW - what software are you using to put the details like arrows and words on your JPegs?

Don´t laugth,
it´s Microsoft Paint :thumbsdn: ......
But I do that quite often and I´m fast with it, because I do some engineering for a company in the U.S. and it´s common practice to comment technical photos with some red arrows, circles and text to make things more clear if you only communicate via E-Mail and phone ...

Congratulations.
Never an easy thing to get a TT from A to B without courting disaster. :tears:
I had the same reaction when looking at your first photo."Is that snow?"
Then I recalled seeing NYC snowbound on the television.I think the last time snow fell where I live was the last Ice Age.
Getting your TT in one piece must almost
make up for missing that C2x(I'm not rubbing it in).Keep lookin' pal,you'll score eventually.
I'd love to compare the 8750 with the PX-2,I'm sure any sane person would be happy to own either. :yes:
Keep us up to date with your impressions. :thmbsp:

Too bad. All those unobtanium parts in the land-fill somewhere.Jon S said:

All they do is toss them in the dumpster behind the post office.Jon S said:
I live in a very small town and once I got a vintage radio that was smashed by the post office. After the claim was paid, I asked the postmaster what they did with damaged merchandise. He said they just threw it in their dumpster. Then he said, do you want this broken thing? I said yes, I might could use it for parts, so he simply handed it to me.
Probably wouldn't work this way in a larger town, but all post offices have dumpsters behind them.

They threw a PS-8750 into the dumpster ?
Does this mean it´s passed on ?
It is no more ?
It has ceased to be ?
It's expired and gone to meet his maker ?
It´s a stiff ?
Bereft of life, it rests in peace ?
It´s electronic circuits are now history ?
It's off the twig ?
It's kicked the bucket, it's shuffled off this mortal coil, run down the curtain and joined the bleeding choir invisibile ?
Is this an ex-PS-8750 ?

that's what happened to my Hasselblad EL/M (limited edition mind you: with a little moon on the front, to commemorate the 10th anniversary of july '69): a few months after the burglary it resurfaced somewere but was so badly trashed that it was deemed completely unrepairable by Hasselblad FR and Hasselblad SW.
I asked my prof. insurance if I could keep it just for the souvenir (my 1st publications I had done with that EL/M etc) since there was no way it could ever be repaired (should have seen what was left of it) but... NO. And NO again. And again NO. So it slept on a shelf in some vault for 10 years and then got to the dumpster. Still miss it, and the souvenirs.
Poor Blad - all alone on a shelf in a dark vault.
Poor 8750 - all trashed and dismembered in a stinky landfill.
