I love stuff like that. My dad's got one of these: http://www.thevalvepage.com/radios/bush/vhf71/vhf71.htm (or at least something very similar) and it has the most beautiful sound. Dad's is in much better nick than the one on the page, too (though not as good as your grandfather's radio -- it's seen regular use for, I guess, 40+ years). He's also got a reel-to-reel tape deck and a record player of similar vintage.
