Lizensierter Nachbau "TELEFUNKON D" bzw. "E304" mit kleinen Abweichungen (metrische Gewinde, andere Übertrager und Bauteile etc.).

Tuning by variable condenser and variometer coupled on a single shaft; 180 to 700 metres; (with load coil 1800 to 2800 metres; see photo); This principle used later by Telefunken for the "TELEFUNKON D" or "E304" which was a licensed copy of the RC with minor variations e.g. metric thread / different audio transformers / slightly different tube socket sleeves / different capacitors and resistors;
