• Notes

• Similar to Million G-401

  Case is similar to KOBE KT-6 (see marking on the back) but with a 4 transistor chassis and very early Hitachi versions though KOBE KOGYO (Brand: TEN) already developed a lot of own transistor types at this time.

  Replacement battery Cat. No. R-7244

  The case was inspiration for the German RFT model Sternchen 57/69TT, although the circuit technology differs significantly.
