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

You need your dealer or TechDas to get involved.  There are no electronics geniuses here, much less even a run of the mill EE. I guess you should do the obvious checks, like is anything dragging on the platter?

You need to contact the dealer - TechDas (Japan) will tell you that as well.  Hopefully its a simple fix and you won't have to send it in.

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
