Aber: Gemäss internationaler Sprachregelung führt der Radiokatalog Band 1 alle Empfänger mit aktiven Bauteilen als RADIO. Wir unterscheiden hier ebenfalls nicht, ob mit Röhren bestückt, hybrid, mit Transistoren oder/und ICs.

Made in 1927-1928, probably by a small Belgian (Walloon) factory or workshop. All binding posts are situated on the front panel: on the left binding posts for the frame aerial, in the middle connectors for the different voltages, 4V, 40V and 80V, on the right jacks for headphones and loudspeaker. The arrangement of the front is perfectly symmetrical.
Valves from left to right: mixer, two i.f. tubes, detector, and two l.f. tubes. Situated in the middle are three adjustable i.f. circuits. Oscillator coils are by Belga, condensers and resistors by Alter, Mikado and French firm Wireless. Transformers by Cema and Transfolina (a brand name of S.B.R., Société Belge Radio-Electrique). Tuning knobs (with fine tuning) are also by S.B.R. Dimensions: 29 × 61 × 30 cm.
