From: Patent Tactics, George Brock-Nannestad



Hello,

I'll second Karl on his support to Tom's suggestion. Unfortunately, you 
cannot get those "cheap" CEDAR boxes any more, to my knowledge. There is one 
consolation, though: ELP, the Laser Turntable people, do now provide a 
one-knob noise reducer that seems to behave very much like the old CEDAR 
DeClicker. And it seems to be about on third of the original CEDAR box.

I think that you would get at least 95% of the possible improvement, which is 
far more than some reissues provide you with.

Best wishes,


George
