- Anotaciones
- At 08/1946, Matsushita Electric put the first all wave radio Model 8A-1 on the market. This set used available tubes only. 6D6 and 6C6 was prevailed for TRF set. UY-76 was abundantly stocked in the market. This model used strange circuit to use such tubes. UY-76 was used as diode detector, and 6C6 was used for first audio stage. Design of this model was suitable for Japanese market. Similar design became de facto standard of Japanese radio later. This unique circuit using available tubes probably had some problems. In 1948, Model 8A-1 model changed into Model 8A-2.
