I've had a fondness of Sony since my parents brought home a tiny portable Sony TV years ago. The screen was about 5" diagonal and it had a battery pack that must have been around 20 D cell batteries, it was huge. Those early impressions left good memories and probably programmed my brain to like the SONY Logo. Lately I've been looking for some of the early 70's mono boxes and have had some success finding nice clean examples that reflect high build quality not seen since. One of my newer finds is the Sony CF-450, one of their more popular radios in the 70's. This little guy is heavy without the four c-cell batteries it needs. Most of the buttons are metal clad and have a positive feel when you change positions. The tone and volume have a nice amount of resistance and are nice and firm. While the handle looks delicate, it's very substantial with metal plated sides and the best part is a detent at the top and bottom so it makes a very nice click when it locks into position. At the time these were made, SuperScope was the US Distribution Channel for Sony, and as most of you know by now, SuperScope owned Marantz. I have to believe that SuperScope borrowed components from these units and filtered them up to the CD and later the PMD line of recorders. I haven't had the chance to open up the Sony yet, and don't know if I need to, to confirm the design. I also don't have any c-cells at the moment and this takes a four prong plug to power up. I think I can use a radio cord if I can isolate the two right prongs. The upper two prongs are closer together and I can fit a cord on but if anyone had fired one of these up without the big cord let me know.
