Radiomarelli was the radio-tv division of Magneti Marelli, a motor magneto company that still produces devices for car ignition, injection and other car and motors related electronics.
In early 1930's it started to made in Italy some American Bosch models with only slight difference (cabinets and multi voltage power transformer) using initially Arcturus blue tubes. Just later was created FIVRE, the Marelli's tube division and started a collaboration with RCA, so RCA tube types were made in Italy by Fivre. This collaboration was effective even for sets: almost all Marelli sets were "american style", this collaboration continued up to Radiomarelli closed down in 1970's (the brand still exixts but as most of historical brands now is only as a rename for shitty poor quality imported sets) excepting the WW2 era in which some odd tubes were designed in Italy, sometimes with the same name of USA tubes but totally different. (6BN8 is an example: in Italy and France a octal about like 6B8, in the rest of the world a noval dual diode triode) After WWII the collaboration restarted, and some 1960's Radiomarelli TV are very close (or almost clones) to RCA models, this also justify the presence of a selftransformer in some models to adapting the mains voltage. The first Marelli color TV in 1967 was also substantially a RCA chassis modified for CCIR standard and PAL color system, and obviousely with a different power transformer.
Due to the Fivre American tube production in Italy, a lot of Italian sets used American tubeline and consequentially american style schematics but only Marelli look so American shaped!
Some manufactureer (Italian Siemens, Allocchio Bacchini, Firte used a melting pot of USA and european tubes in their sets, and even the circuits were an "hybrid" of two styles. I don't like so much these sets.
Geloso models were a true Italian exception: also American style in circuits, but look is unique, typically Geloso at first sight. John Geloso was from an Italian family but born in USA and in 1920's returned in USA at PILOT radio, and also studied at Cooper Square University. In early 1930's come back to Italy and found the Geloso corp, initially producing in kit form only then even complete sets. Initially all american style projects (except some rare kits adapted for European tubes). I presume continued a sort of collaboration with Pilot, the early Geloso fm tuner had exactly the same tubeline of Pilot, but this is an unconfirmed mine idea. Only the last production in late 1960's moved totally to European tubes and Philips ispired circuits, then Geloso closed down in 1972 and was told this was due principally to exasperate syndacalism in the factory.

Returning briefly to Radiomarelli, all Marelli component (caps, resistors, transrformers, speakers...) are American shaped, Marelli made in Italy on RCA licence even a clone of the famous RCA74JR ribbon microphone....

After WWII RCA by itself also opened a tube factory in southern Italy (Sicily) that produced RCA Italy branded tubes. (Probably consequentially of Marshall helping plane)
