In that pic, the receiver/tuner appears to be a mid-70's Pioneer (possibly)? My first stereo was a Pioneer receiver and it looked almost exactly like that (I think it was the SX-nnn series).
Nice reel to reel rig as well.

Pioneer made some really nice stuff back then. I owned one of those racks and had rack mount equipment. That was in the early 1980s, although the rack and some of the equipment may date back a couple of years prior. I owned the (Pioneer) cassette deck that went in the rack. I picked the rack up on closeout with pieces of some of the rack mount kits from a retailer going out of business for about $90 and bought about $50 worth of parts to make the rack mount kits and what I had complete. I think the few rack mount kits and rack I had at that point were $700 list. I had a friend who had the reel to reel and he wanted the cassette deck and the rack and I he eventually traded me a Nakamichi 680 cassette deck for the Pioneer Cassette deck and the rack and the kits.
