I have a mcintosh MR67 tuner which needs some work (intermittently noisy and low sensitivity)and was wondering if the modaferri mod($500)might be a good option. Does anyone have have experience with this mod and or/repairs. The tuner is in good shape physically and sounds better than the NAD that it replaced. Thanks
Hard to say what is exactly wrong with your unit but have you tested all the tubes? I have had several MR-67s and MR-71s and a host of other tube tuners and have miracles happen with tube change to high quality NOS Tubes.
