Some good comments here regarding Rega TT. I have had my Planar 3/RB300 since 1984 when it was partnered with original Rega MM cart, A&R A60 Amp and lovely Heybrook HB1 speakers. Great system for the price point. I still have the A&R but the Heybrooks disintegrated.
Now a couple of years ago the Rega 240v suspended motor capacitor packed up so I replace the motor and board with expensive High Performance Motor Upgrade Kit's 24v DC motor & 'tuned' board. This is stuck on to the thin Rega plinth veneer of this model with thin adhesive foam pad so is now directly coupled to the plinth.
After a recent oil/bearing change - which really tamed the bearing noise - I noticed a hum from the motor, most noticeable when the lid is closed. Detaching the platter/sub-platter & belt and disconnecting the amp/tonearm cables showed the motor noise was still there. A stethoscope from my partner means I can clearly hear the low frequency tone through the plinth veneer.
This sound does drop off quickly the further from the motor you listen but I without a microphone I can't say if it reached the tonearm/cartridge.
