I got lucky and located a NOS McIntosh MR-67 FM tuner. I restored the power supply -- up-graded the discriminator, Multiplex board, and audio section with parts such as stacked-film polycarbonate capacitors, Teflon capacitors, and modern Roderstein metal-film resistors, and the like. The sound I have been getting from this vintage yet text-book FM tuner is as good as the FM station broadcasting. I mean that in some cases it is as good as a good CD. Before that I had a Magnum Dynalab Tuner -- that by direct comparison with the MR-67 was, in my opinion, a piece of junk. The MR-67 design followed the established standards of the original FM stereo patents. NICE!!!
