Matsushita Electric Industrial Co., Ltd., Osaka. Marked Panasonic / Matsushita, Made in Japan. Seven-transistor AM pocket radio, about 1962. Same family was sold as National in Japan and Panasonic on the export badge. In the MicroBasement it sits after the crystal sets and the Globe Patrol: the store-bought superhet a kid owned while still building kits.
No shortwave, no FM. One band, one job: local and night skywave AM in a plastic case.
Konosuke Matsushita founded the company in 1918. National was the domestic radio brand. Panasonic was the name put on export goods so a Boston or Salt Lake shelf could sell a Japanese portable without the National badge. By the early 1960s Japan was pouring 6- and 7-transistor sets into the same stores that sold Radio Shack diodes. The T-7 is that wave: not the first transistor radio (Regency TR-1, 1954; Sony TR-63, 1957), but the common good one.
Crystal set: no gain. Globe Patrol: regen, four bands, a squeal, and the world through a bedroom window. T-7: superhet in a pocket, no soldering required. Different lesson. The kits taught the circuit. This one taught that a factory in Osaka had already productized Armstrong and put it next to the 1N34 drawer.
