- Koyo KR-6TS1. RadioWallah (tabiwallah.com). (pages: front, rear, inside, rear cover)"Koyo's first transistor radio, the KR-6TS1 went on sale in the spring of 1957 at a list price of ¥14,000, (with leather case and battery). This model is distinguished by the comet-shaped design of its speaker grille and tuning dial. Not the flashiest set on the block, but a pretty, early Japanese transistor radio nonetheless. "
