TechDas Speed Issue

Hey Folks,

 

Fortunately for you I have not been around in a while.  Hope everyone is well and good.  
 

My Airforce Premium III S has decided to switch on its own to manual speed mode and decrease the speed to about 43 rpm.  Happened twice in two days while playing the second side of a 45 rpm LP. Haven’t noticed it on 33s.  I turned off the power supply at the rear and let it sit overnight.  No joy.

Y’all heard of this?  Fix?

 

Thanks,

Robert

Dear @robob  :I don't know the age of your TT or hours playing it.

 

Maybe what could needs is a new belt and clean the metal parts where the belt drive it.

OK,  I thought maybe somebody had run into the issue.

And no, nothing is dragging.  It is an air bearing with a separate compressor for the bearing and vacuum hold down.  The power supply and and speed controller are in a box with the compressor.

Y'all take care,
Robert

Try to readjust speed again with belt tension - like from the beginning. Go with lowest tension as possible. 

Good luck!
