• Notes

• The model Spica ST-600 from Sanritsu Electric Machine Co. was available in different cabinet colors.

  There are different dial scale designs (arrows, 5-point star, 3-point star). The model was also made with alternative transistor complements, e.g. 2SA52, 2SA49, 2SA53, 2SB54, and 2× 2SB56.

  At least two circuit boards have been used.  The easiest way to recognize them is to look at the I.F. transformers which either may be on the same line, or offset.  The relationship, if any, between the different circuit boards and the different dials is not known with certainty.

  The ST-600 comes with its original gift box, leather carry case, leather earphone case, earphone, instructions and warranty card.

  Sanritsu released a vertical version of this radio, model Spica ST-608.

  There is also a similar seven transistor variant with a plain gold textured speaker grill named Spica Super 7. Other radios with similar appearance are found under the names Holiday, Impala and Spiket Deluxe.
