• Notes

• NOTE:- Il modello 304 fu prodotto dalla Radiomarelli sia col marchio Radiomarelli, e in tal caso lo troviamo indicato con la sigla RD 304, che col marchio WEST, in questo caso indicato con la sigla DS 304. Lo schema elettrico è tratto dal Volume II degli "Schemari di Apparecchi Radio a Transistor" editi nella prima metà degli anni '60 dalla CELI, Bologna (I). Esteriormente il modello 304 è molto simile al precedente modello 301 (sia marchiato Radiomarelli che WEST) e spesso viene confuso con questo. Osservando bene entrambi i modelli si nota a colpo d'occhio che nel modello 301 sulla grande manopola di sintonia vi è un pomello col disegno di una stella che invece manca nel modello 304: inoltre anche la numerazione della scala di sintonia varia da un modello all'altro. Internamente, il modello 304, pur essendo anch'esso ad una sola gamma d'onda (Onde Medie), è completamente diverso dal modello 301.

  NOTES: - The 304 model was produced by Radiomarelli both with the Radiomarelli brand, and in this case we find it indicated with the initials RD 304, and with the WEST brand, in this case indicated with the lettering DS 304. The wiring diagram is taken from the Volume II of the "Schemari di  Apparecchi Radio a Transistor" published in the first half of the 1960s by CELI, Bologna (I). Externally, the 304 model is very similar to the previous 301 model (both Radiomarelli and WEST branded) and is often confused with its predecessor 301. Looking closely at both models, you can see at a glance that in the 301 model on the center of the large tuning knob there is  the design of a star that lacks in the 304: also the numbering of the tuning dial varies from one model to another. Internally, the 304 model, although also having only a wave range (BC band), is completely different from the 301 model.
