Turntables thump when turning off?


Why?  I have used 4 different tables and three phono stages in 2 different systems and all of them produce a pretty loud thump when turning off especially, sometimes when turning on.  I have been muting the system each time I turn off as it seems a little much to be letting such a thump reach the speakers.  Is there a cure?  lift grounds?  arrange cables? I was getting a pretty decent hum at times and I've noticed careful routing of the cable to the phono preamp makes a huge difference in this.

The thump is loud, very loud if it's at the full volume I would play an LP at.  I guess you guys are saying it's normal and I just have to live with.  It's there no matter the table or phono stage and even does basically the same thing in a whole different system.  It's a VPI classic 3 and Rega RP8.  I had Nottinghams before and those don't turn off ever so maybe that is why I didn't ever notice until now.  You have to stop the VPI motor after every LP side since it uses the center weight and periphery ring.  The RP8 I can just snag the LP off without stopping it.

You know what the Doctor says to patient?

It hurts when I do "x" Doctor-then don't do "x"

 

Contact VPI.  Some of their turntables had an issue with making a pop when powered off.  They sent me a capacitor for free for my Classic 2 and it was a pretty easy fix and resolved the issue.
