Geloso

Geloso, founded in 1931 by Giovanni Geloso, was an Italian manufacturer of radios, televisions, amplifiers, amateur radio receivers, audio equipment and electronic components.^[1] its headquarters were situated in Milan, Viale Brenta 29.^[2]

History

In 1931 the company started the production not only of radio sets but also most of the electronic components with which they were built and, over time, also developed and patented many others. After the Second World War, Geloso expanded and expanded his production, becoming from 1950 onwards, a point of reference for enthusiasts of consumer electronics and hobbyists.The many products under the brand name Geloso were known throughout Italy and much appreciated abroad. The output consisted of innovative products known for their high quality, solid construction and reasonable price. The main production consisted of radios, amplifiers, tape recorders, televisions, kits, and professional laboratory instruments. These were complemented by components such as capacitors, resistors, potentiometers, switches, connectors, transformers and microphones.^[3]

At death in 1969 of the founder, Geloso had become an empire of eight production plants, with a capillary and efficient sales network. Production continued production until 1972, when it closed permanently. There were several reasons for this closure: fierce foreign competition, managerial problems, union demands and massive indebtedness to banks.^[3] Emblematic the definition of "Neo to be erased" given by Vittorio Valletta (a person notoriously linked to Mediobanca) in relation to the electronic sector of Olivetti.^[4]

Geloso Technical Bulletin

Geloso was considered a good businessman, but also someone who wanted to share his passion for electronics. In 1931, he produced a free quarterly publication known as the 'GELOSO Technical Bulletin'. This contained everything needed for the repair and development of its equipment, but also and especially, tips, instructions, characteristics, circuit diagrams and everything that technicians and enthusiasts needed to know.Those were the years when there were no training centres; moreover schools specialising in electronics were extremely rare. These technical bulletins had the merit of spreading, in a simple and clear manner, knowledge to people who otherwise would not have been able to learn and develop their passion.^[5]

Assembly kits

Geloso's contribution to the knowledge and popularization of radio technology was considerable, thanks mainly to the assembly kits that enabled the purchaser to build a television or radio receiver, or even radio amateur equipment, almost from scratch.The starting point was the provided metal chassis onto which the components were fitted. Some pre-assembled and pre-calibrated parts facilitated the work. By following the instructions in the bulletins, the entire set could follow a final calibration and everything was completed and ready to be fitted into a wooden cabinet with knobs, buttons, etc., all marked Geloso.^[6]
