Vintage Mcintosh tuner


I would like to add a vintage Mcintosh tuner to my system. The Mcintosh MR-78 and 75 are my first choice tuners but I was also looking at some of the older Mcintosh tube tuners. Any advice would be appreciated.

I purchased an MR71 a year ago and absolutely love it. I still can,t beleive that a tuner that is over 40 years old can sound this good. It is built like a tank and the retro style looks beautiful... a piece of art! They don,t build them like this anymore.
I am happy with my stock MR-67. The good thing about classic McIntosh gear is that you can still have it serviced. Although I've never used him, I hear that Terry DeWick does a great job aligning and bringing McIntosh tuners up to spec.
   I have five Mac tuners...the MR-71, 74, 77, 78, and 80. I strongly recommend all but the MR-80. I can't recommend the MR-75  I have heard it and does not compare with other Mac tuners
I'm not sure why you don't like the MR-80, but I think it's one of the best FM tuners ever built.  I certainly plan to keep mine.
