New member here, and current member of the FB Vintage Hifi and Stereo Enthusiasts and Vintage KLH Audio groups. I've been collecting 70's era KLH for years with a particular interest in the Research Ten series. I own the following models: CB-6, CB-8, CB-10, CB-10x, CB-12, CL-3, CL-4a, Classic 5, SCX-2, CT-38 Pistol, and CT-44 Magnum. Still trying to track down the CB-430, Classic One, SCX-3 and Classic Four. There was also a Research X Model 60 turntable, btw.
