From: Patent Tactics, George Brock-Nannestad
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.
