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

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.

A very heavily modded Sansui TU-717 and a Dyna FM 5 very modded by Frank Van Alstine. Both are terrific. The roof mounted APS-9B antenna , low loss balun, and RG-11 cable all help too. 

My Tandberg 3001A programmable FM tuner needs a new home.  My listening has shifted online.
