    Dual 1264 clip spring question

    I have been through it with this cursed turntable, but I am being called by a higher power to get it fully restored. It’s quite an abusive relationship I have with this deck. The current issue I am facing is that the clip spring is missing which I hope is the reason I can’t switch from 33 to 45...

    Dual 1229 is just a touch slow and I can’t quite figure it out.

    Hello. New member here. So I cleaned up a Dual 1229 that was actually gifted to me and the motor seems to be a touch slow. I removed almost, if not all, the old grease and replaced it, took the motor apart to re-oil the felt, re-glued the strobe ring under the platter as well as a lot of...

    Akai GX270D Speed control question.

    My Akai GX270D at 7 1/2 ips runs fine both directions. But when I set the speed at 3 3/4 and punch play it always energizes fast and then slows down to the 3 3/4 over several seconds. It does the same thing both forward and reverse. Once you hit stop, it's like the capstan defaults to 7 1/2...
