Any vintage tuners with a small footprint?

For vintage, Technics ST-C01 or one of their other micro series tuners may fit what you're looking for. For non-vintage, Parasound Z-series and Teac Reference come to mind. Pro-ject also makes some very bitty little components including a tuner, but I know absolutely nothing about them.

The Meridian 104 was a decent tuner with a small footprint.

One of the better tuners made was a Naim model I heard 20 years ago that had an extremely small front profile. I don't know if it is cheap as a used model, but I would suspect it still commands a decent used price.

Meridian 104 as mentioned, also Quad.

Hi hifi hit it right on the head. I paid $60 including shipping, and it blows away some of the hi end tuners I have. Things do get better and cheaper.
