I agree with David: 400-CX-2 (with the early-style knobs). The minimal ventilation argues against any sort of power amp. I think that backdrop was probably either in Mr. Fisher's Manhattan co-op or his weekend home in Washington, CT. Below is a less cropped version - probably shot in 1963 - which reveals a companion tuner. It's got to be an MF-300 but the Tune-O-Matic buttons look too small. Perhaps a design variation?
Also note the 400-CX (-2?) from a 1963 brochure with the later-style knobs. At least I'm pretty sure that's a 400-CX-2 since the 400-CX has the 4 oval push buttons in the center, right? Is it possible that the one in the photo is the one from Avery Fisher's estate that sold on eBay in 2010? It was discussed
here in this thread.
As someone with somewhere between 5000-7000 classical records,I would love to see Avery's record collection.
