Do any still use an older high end tuner from the past?....

I'm listening to a Nakamichi ST-7 in my basement system. Not really high-end but it still sounds really good with the only NPR/classical  stations that are worth listening to in my area (WGUC and WVXU). Using a really cheap wire dipole on the wall I get 4 out of 4 bars on the strength display. Upstairs the built-in tuner of my Marantz 8805 prepro is surprisingly good hooked up to my attic space FM dipole. The advantage of the Marantz is that I can get internet radio, and so of course there is a huge choice there. SQ of internet radio is very spotty, but the BBC and Classic FM feeds sound quite good. In any case both of my FM options sound better than a Marantz ST59 tuner I bought in the late 90s to feed my Sony preamp back then.

I have owned many tuners over the years, but my favorites are my present three:  Mac MR71 and Marantz 10B, both recently refurbished by Richard Modafferi, who did an amazing job.  (When he opened up my MR71, he discovered that he had performed work on it in 2000, some years before I owned it!)  I also use an MR78 that I purchased slightly second-hand in 1978.  It has had only a light tune-up to replace some lights, etc., in all that time, and it still sounds amazing.  These are great units that provide spectacular sound reproduction; I haven't found anything with today's technology that compares.

I use a highly regarded Harman Kardon Citation 18 tuner. Works very well, looks great and the build quality is mil spec. Introduced in 1977 for $595.00 and only sold in very limited numbers for 2 years. I lucked out and found mine on CL, the owner had just done a recap on the plug in boards, was moving so sold it very cheaply. It was a lucky find to say the least.

how about an SAE MK VIII?  The problem is that the nixie tubes have gradually gone out and there is no way to determine what station you are tuned to.

Over the years......

Lux T110, Tandberg 3012, McIntosh MR78, Scott 4310 (Foster Blair fixed it up for me), Three different Scott 310-B w 335mpx (all fixed up by Foster), Yamaha CT-7000, Sansui TU-X1 (aligned, upgraded, recapped).

By far the best is the only one I still have.  The Sansui.  One good classical station in the area still makes it worthwhile.  Channel Master TV-7? Antennae mounted in attic.  Incredible sound quality.

One of the Three Scott 310-b I had was my prior vintage favorite, simply terrific.  The 4310 was probably the most exotic but a little scary with all the controls and so many tubes.
