After some time researching the available public resources, I understand that at least two different main chassis variants were made, one using early Sony "oval" transistors, and the other using OC glass packaging transistor series.

As for the variants, schematic diagrams exist referencing the radio model as EB-180 and also as EB-180A model. Apparently the only difference between them is the use of a removable telescopic antenna on the EB-180A model, despite both models seems to have been produced using either Sony or OC transistor series.
