  • Notes

  • The model KOYO Six Transistor was made in different colors.

    We received pictures from a guest with a 9-Volt block battery and made a variant "9 Volt" but today we doubt this variant for some reasons - but let it be - explained.

    This model with 4 AA batteries is common and may be the only one. The common color for the back cover is dark green. They have also a brown colored leather case with a strap. Hitachi metal germanium transistors are used. On top of that there is also the "Six Transistor Deluxe" with the same case.

    See similar models reported under Koyo Six Transistor.
