The one piece of gear you will never sell

I have been in this hobby long enough to know to never say never. 

My Marantz 2270 receiver which I use only as a tuner in an all modern Audio Research/Wilson Sasha system. But that is purely for sentimental reasons---looks, sound and the fact that I purchased it in 1971 as a phase out for $209.00 and it was my receiver in high school, college and beyond. Everything else is fair game. 

Never say never, I get that, but my Zerostat's ain't going nowhere. Didn't say never!
