  • Notes
  • This model was one of first JRC radios after the war. Model R-101 receives the low end B.C. only. The small wooden cabinet was painted like Bakelite. It uses new MG tubes "N series" licensed under Telefunken Germany at wartime. The name was changed from N series into "12G" series. These tubes use octal base but the connections are German style. Heater voltage is 12.6 V. No compatibility is kept with American metal or GT tube. American metal tube were manufactured by Toshiba at wartime. Many used American metal tubes have been put on the market as surplus from the occupation forces. "12G" series was not accepted by the Japanese market. JRC stopped production of original tubes. In 1948, they released new mode NR-5A using ordinary tubes.
