If  you  notice  hum  in  the  system,  remove  the  turntable  to  phono  section  interconnects  and 

replace  them  with  very  cheap,  standard  interconnects.  These  are  well  shielded  and  should 

eliminate the hum. If the hum goes away, get quality, well shielded interconnects. 

 

After at least one year of use the platter bearing should be re-lubed with PTFE super grease.  

The motor will need to be lubricated with 1 drop of 40-weight motor oil below the black drive 

pulley and right on the brass piece. 

 

You can experiment with mats but you need to adjust the VTA setting when doing this.

The answer is to ground the motor and  system properly.  A line filter that floats the 

grounds will not allow proper grounding of the phono system; the phono system must 

be grounded!  Phono is not like a CD player and if this is your first table or your return 

to vinyl after a decade or so you must remember that phono amplification can be 1,000 

times  higher  than  CD  or  streaming  so  any  noise  that  gets  into  the  system  will  be 

amplified much more.  Kill the noise with proper grounding and your system will sound 

better. 

 

A pop on motor turn on or turn off:

In some systems the phono section is not well shielded and will pick up the EMF created 

by the switch opening to turn off the turntable.  If your system is like that you can get
