If you have an older Planar 3, the start up rattle is normal, but not the continued rattling. The new P3 motor has a different mounting scheme which shouldn't rattle at all. This motor is offered as an upgrade to older tables for 155.00. I would recomend this as an upgrade if, in fact, you don't already have it.
Start Up Rattle on Rega P3
I have just purchased a Rega P3 and have noticed that when I start it up I get a slight clunking sound while the platter comes up to speed. The clunking dies down slightly but, does not entierely go away and is evident on quite passages. Does this sound normal? And does anyone have any ideas on how to fix it? Thanks "getting back to LP's"
