  • Remarques
    • This unit is part of the so-called "Radio-Puzzle" which is modular in conception by placing every stage in a different module. It could be configured not only as a radio with different principles but also as telegraphy receiver and writer or as measuring equipment.
    • By combination of different units, one gets a complete radio or other application.
    • All connections are made with wires in clamping screws.
    • The clamping screws for the filament "A" battery and the plate voltage "B" battery are placed at the same height/depth so that they can be easily interconnected. The whole powerline setup is made as a daisy chain.
    • These units were initially manufactured and commercialised by S.I.B. from 1920 on before SBR took over the retailing under their own label in 1922.
    • Used coils on these units are Disco-self 1922 or the preceding SIB Disco-Self 1920. They are optionally mounted on the side panels of units A, B and E. The obtainable frequency range with those coils was approximately 13kHz (23000m) to 1,75MHz (170m).
    • The following modules of the Radio-Puzzle are known:
      • RPA = Tuning module and optionally a crystal detector. Despite the fact that this unit doesn't need power, it has power connectors to pass along the current to the next unit;
      • RPB = Tuning module with RF amplifier and detector;
      • RPC = RF amplifier with regenerative feedback or an autodyne with a "Compensateur"1 and optionally a detector;
      • RPD = RF amplifer with RC2 interstage coupling (autodyne amplifier together with RPC). However, this unit can be used as LF amplifier stage also;
      • RPE = LF amplifier with interstage transformers;
      • RPF = Tube detector (not an amplifier) to drive a morse writer or a repeater morse key. Driving power for the following relais after this unit comes from the preceding LF amplifier module (see schematic and explanation at the bottom of this page);
      • RPG = Variable coupling unit for 2 disco-self coils from which 1 has fixed position on the preceding unit RPA, RPB;
      • RPR = Variable coupling unit for 3 disco-self coils from which 1 has fixed position. It could be used to make a regenerative circuit by variable induction.

    Alternative for TM tubes: Marconi_R

    1 Compensateur: the differential variable capacitor to control the positive and negative feedback. Not a butterfly capacitor.
    2 Resistor and capacitor.
