model 7 transistor
Made in Japan in the 1960s - MW radio - 7 Ge transistors, mix of several brands, made in USA and Japan - supply by 1 special cell for 9V - nice small radio of good electronic quality, but the plastic case is of bad quality, unexpectedly for such a cheap radio sound and reception is very good - it has an OTL output stage - one should think this is a vertical radio but in fact it is a horizontal one: the ferrit rod is placed horizontally, see picture below.
Here the interior of this remarkable radio. On top you can see two of the seven transistors in TO-5 package, TI made, the ferrit rod is on the bottom.
