You can see the double-layer power and volume switches to the right of the upper battery holder. Below the right end of the same battery holder are a pair of earphone jacks, and below the speaker magnet is a connector for an external power source.

The large speaker and ample output produce excellent sound. And here we have another early Hitachi with the slick "leak-proof battery cases" that have a cap at one end and the holes at each end are just large enough to allow the batteries to make contact. These battery cases are also found in the TH-668 and TH-667. The oval transistors pictured above only appear in the earliest production WH-667 units.
