The Teletron Companion Transistor Receiver |
 |
|
A 3 transistor radio kit using a Mazda XA102 (or Red/Yellow spot) and 2 Yellow/Green spot transistors from 1958. The circuit is unusual in that there is no tuning capacitor instead a coil is used which is wound on a long former, the internal core is again long and adjustment is by screwing the core in and out.
The radio has long and medium wave coils wound on the same former. |
