Vintage DD turntables. Are we living dangerously?

pbnaudio,

Sorry for the delay in responding - I check this thread less often than I used to.  Yes, adjusting the bearing cap does change the height and your instructions are probably right.  I diddled with that for quite a while but then I changed the washers that the motor unit is mounted to the frame through. Here is a response I posted on the the nude turntable thread three years or so ago where I discuss that change.  It made adjusting the motor height much easier if nothing else.

pbnaudio,

As you are working on setting up a TT-101 I have a question:  can you consider what it would require to pull the power board and transformer out of the tin can and mount them in a separate box?  I would love to do this as it is a source of both vibrations and rf emissions.

Thanks.

While I am posting to this thread I wonder if others in our situation are keeping an eye on the latest Technics coreless dd turntable.  I hate that they chose the SL1200 model to follow and hope that they will consider the SP10 model for a new even higher end offering.  I see this tt as a suitable replacement if my TT-101 pulls the plug.

Aigenga, Vibrations and EMI can come from the power transformer more than anything else.  It would not be much of a trick to re-mount it outside the chassis on a separate base.  And you might be able to do it with the rectifiers and filter capacitors that together with the transformer constitute the power supply. However, I would be very leery of moving those servo and motor control circuit boards off-chassis.  Peter already told me privately that he sees this as a bit of a problem with the TT101, whereas you may know that he did do it successfully for the DP80 in the context of his aftermarket plinth.  I too will be interested in his take on moving the circuitry off-chassis, once he solves the problems with his unit.
