[Phono-L] Columbia A Cylinder machine spring

Anyone know what length/width/thickness they are supposed to be? Would they be the same spring as found in open-works machines like the AU? Someone fudged in the wrong spring on my A and I would like to make it right. Thanks, Ron L ___ Phono-L

I think I heard years ago that all Columbia springs are the same size.  I used one from a Grafonola in my AU and it worked just fine. Dave --- On Mon, 11/29/10, Ron L'Herault lhera...@bu.edu wrote: From: Ron L'Herault lhera...@bu.edu Subject: [Phono-L] Columbia A Cylinder machine spring
