A Technics Frankentable

I have checked the RPMs with the paper VE strobe disk and the 0% pitch looks just about right. I will need better light to read any fluctuations. When set to stabilize the 50 Hz/33 rpm strobe dots the paper strobe reads obviously fast.

I think we have decided that the labels of the dot rows on the turntable do not apply to your platter.
You might be best to ignore them, set your speed with the VE strobe disk, and enjoy some music.
I have found that a cheap LED night-light, on a short extension for convenience, makes a perfect strobe.
BTW, you are on 60 cycle current.

Remove the platter and the under platter dust cover. On the main board you should see what look like a metal open screw it will be located sort of to your left and is rite at the edge of the plinth. You can adjust that to line up the LED's on the pitch control............. It will allow you to move to either the + or - depending on what you need to do..........

Hi Brisbane,

Thanks for the info. I located the adjustment point, labeled VR425, and looked up the procedure in the service manual (actually the manual for the SL-1700MK2). To do it with some accuracy the procedure calls for the use of a frequency counter which I don't have or know how to use. Are you suggesting that I can eyeball this while using the wrong platter?

hey analogaudio,
Aren't the SL-1600MK2 platters slotted for the optical disc size sensor?

Jim

Yes they are, my error, the 1600mk2 platter would be usable but wasted on a 1710.

Hi Brisbane,

With all do respect, this is not the way to do it....
This way you loose all reference incase you might put on a correct platter
The MKII strobe is on a other internally regulated frequency than the MKI version and is not suited for the mentioned platter.

Jim,

I agree with Alec, ignore the dots, and make sure that your speed is accurate with an external strobe.
In all the 23 years of ownership, my SL1200MKII has never had any speed issues.
Your table is quartz locked too, so if the speed is okay now, it always will be okay, and if you still have doubts, just do the external strobe check.
Be very careful with trying to fit one to the other, you will be lost in space before you know it.
In my opinion, if you want to see a steady strobe, buy a platter from EBay for 25 bucks, I don’t know if you have damping underneath your present platter, the one you need have, or at least will, because only 1200 platter are available. In fact you can sell your present platter to me than if it is in good shape, I have an SL1700MKI and I can do a little experimenting, however I don’t know if the shipping costs to Holland will add to much to the price....

There are a few different part numbers for these platters and I am not sure if it makes a difference which I get. I am getting them from the service manuals here at VE.

SL-1700mk2 - SFTE172-01Z
SL-1200m3d (silver) - SFTE172-01Z
SL-1210m3d (black) - SFTE172-01Z1 (Is this just a color difference?)
There is an SL-1200 platter on eBay identified as a SFTE172-01Z3.

I have not yet located a service manual for my TT, the SL-1710mk2. Does anyone have the service manual that list the specific part number?

Did you get my PM? The 1700MKII platter is no longer available.

[scho2684]

The numbers for te 1700MKII and 1200xx are the same, and the one for 1200xx is available.....
So the ones you see on Ebay are OK

That gives the answer on the damping as well....

[jimbo1421]

Hey Marco,
The part numbers are not exactly the same, but a customer service guy at Panasonic assured me that there were no differences except price. (???)

I bought the service manual for the SL-1710mk2 online. The parts list shows the platter P/N is SFTE172-01Z.

By damping do you mean braking?

Thanks for your help.
Jim

[scho2684]

No, by damping I mean the rubber lining inside the platter.
On your current wrong platter you dont have that.
The one you have now, rings like a bell without the rubber mat on it
The MKII platters are death (damped with rubber lining)

Marco

[jimbo1421]

Marco,

I see. Mine does ring like that. I look forward to getting a replacement soon. Thanks for your help sorting this out.

Hi Marco,
I have a 1210mk2 and the platter does ring badly without the mat on it.
Perhaps it is the wrong platter.
Does any one have pictures of damped and undamped platters or can describe how the two can be visually identified?
Thanks

[jimbo1421]

I think this eBay item shows the liner. Am I right, Marco?
