Vintage DD turntables. Are we living dangerously?

Using a stethescope (is that sick or what?) I can hear a hum that sounds like the transformer to me: it only sounds when the power is on whether or not the platter is spinning. It makes me think about pulling the power supply out of the tt and moving it into a separate box. Has anyone done this? If there aren't many different feeds at perhaps different voltages then I would think it could be done without spending a fortune. Am I dreaming?

Hi Aigenga,
Strange you should mention stethoscope?........I just bought one last week and have been madly scouring all my shelf positions, motors, platters,,tonearm supports and plinth.
I have absolutely no motor hum whatsoever from the TT-101.....and that's placing the stethoscope on the metal motor surrounds, the aluminium control fascia and even the platter( with the motor on but the platter not spinning).
I'm surprised your Techi didn't check out the working performance after changing out the caps as you said there was noise in the bearings as well?
Something is amiss. Hope you find it?

Aigenga,
Does your TT-101 have the grounding cable attached to it?

Halcro,
I'm glad to hear that someone else is crazy enough to buy a stethescope and go looking for trouble. I hadn't thought of it but you are right that the tech should have noticed that the transformer is humming.
The motor now is beautifully silent, and I tried with and without the ground wire attached to the phono pre-amp but no difference.
Today I am going to see if I can rubber mount the transformer. I might need to replace it. But if there is a way to power it via an umbilical cord that would be best. There is a good write up of this at the KAB turntable site and I sent an email to Kevin asking if he could do it.

A vibratory hum from the transformer is nothing to worry about, as long as it does not intrude on the listening experience. If you had an amplified hum coming thru the speakers, that is another story, but don't worry about the local mechanical hum. Why yours hums and Henry's does not is possibly only a function of the voltage and/or frequency of the current coming from your wall socket vs Henry's. (Don't know the voltage/frequency in Australia.)

Henry, are you using that stethoscope to identify nodes in your shelf? As a doctor, of course I was born with a stethoscope around my neck, and even though I never use one in my chosen field, I have always owned one or two.
