Vintage DD turntables. Are we living dangerously?

Hi guys

Has anyone ever opened the TT-101 engine?

I read on the service manual that inside the engine there are components called "3 hole elements" but you do not see any electronic components at the holes of the engine, and the service manual in several steps is very rough and is not as good as that of the Technics SP 10II

Does any of you know what it is, what electronic components are in the engine or do you have any pictures to let me see?

I think the problem of the low engine power is caused by some element "inside" the engine but if I open the whole engine then it is not possible to proceed with the moving motor in order to find the defective component.

Cheers

I still don't understand what you are observing.  Let me guess: the turntable comes up to speed and works normally for "2-3-5-7 hours" and then...  Here is where I lose you; does the motor stop driving the platter and then does the platter coast to a halt, or what?  In failure mode, do all the lights go out, or not? In your second one-sentence paragraph, are you now saying that the problem was solved by re-soldering some joints?  

I will say this: If you acquire a vintage DD turntable that has not been serviced in a decade or more, the FIRST thing to do is to replace all the electrolytic capacitors.  I say this, because leaky capacitors can cause damage to other vital active components that are not so easy to replace, and this can happen the moment you apply AC power.  The term "leaky" refers not only to the fact that old electrolytics can leak fluids but also to the fact that old electrolytics can "leak" DC voltage.  A functioning capacitor often is used to block DC from entering parts of a circuit where DC can otherwise damage associated components.

Replacing the electrolytics as a last resort is, as we say in English idiom, locking the barn door after the horse has escaped.

Hi Lewn,

the problem is that the cold engine has no power ...... the disch turns for a 50-60 seconds then slows down until it stops.
To start it again, you need to help with my hand, keep the 33 laps for a 50-60 seconds and then stop coming back.
The capacitors are ok, the power supplies are ok, the power transistors inside the turntable work ..... all the electronics have been repaired.

I just want to know what electronic component is that marked on the service manual called "3 hole elements" and that it is inside the engine .... i do not want to open the engine unless it is needed.

Hi lewn,

I have read many old papers and found the problems of your TT-101 written a couple of years ago.

The result of my labors was to make an intermittent problem into a permanent one! Here is the failure mode: The tt comes up to speed based on the tach reading "33.33", but very shortly thereafter, within less than a minute, you will see readings suggesting the speed is off, 33.32 then 33.34, etc, typically. At that point, the motor shudders significantly and shuts itself down; the platter coasts to a stop with no brake action. The tach goes blank, except for the decimal point.
That's the story.

This problem is what happens to my turntable.

Did you find the cause of this, Mr .Thalmann told you what is the problem?
Or better chance you can ask Mr. Thalmann how he repaired your turntable from this defect, what components had to be replaced?

Cheers
