BRAND NEW FRESH RUBBER - *SEVEN EACH* LORD RUBBER GROMMET ISOLATOR W/ METAL INSERTS - REK-O-KUT TURNTABLE MOTOR (These are also used in the Radine L34 turntable and Empire 208 398 498 598 698 models.) Here's the specs for this product from the Lord website: Maximums: Axial Load = 2 lb / Axial Spring Rate = 32 lb/inch This means that as long as your motor assembly weighs less than six pounds for a three point mount or eight pounds for a four-point mount, this grommet will be in spec. I have had no user complaints.
According to one astute fellow with a stethoscope, the lower durometer (softer) grommets which spec at half these values (1 lb & 16 lb/inch) are preferable to use with the lighter motor assemblies. There's quite a bit of discussion and disagreement on these grommets! In any case, I have these in stock so that you have your choice. Just let me know if you want the lighter spec grommet when ordering and I will ship it. Here's a passage touching upon the grommets, written by a contributor to the Audiokarma forum, who has amassed a history of the Empire turntable ("Some Empire Turntable History"). It's a great read and very authoritative! Read it: audiokarma.org/forums/index.php?threads/some-empire-turntable-history.278075/ "Speaking of Rek-O-Kut, this is a good place to address the similarities between the two companies. Both were based on Long Island, New York, both utilized AC synchronous motors sourced from Pabst of West Germany, and both companies even used the exact same motor grommets sourced from Lords of Pennsylvania. Both companies also featured heavy cast platters balanced for perfect balance with a built-in 45 RPM adapter and bearings that even today are marvels of precision engineering. Styling is also similar, although Rek-O-Kut’s are more utilitarian with their boxy bases, gunmetal gray baked on finish, and red rubber platter mats. Rek-O-Kut also concentrated on idler driven turntables, but the one belt drive model they did produce is uncannily similar to the Empire." FAST!
