Geloso
 |
Geloso, founded in 1931 by Giovanni Geloso, was an Italian manufacturer of radios, televisions, amplifiers, amateur radio receivers, audio equipment and electronic components. Its headquarters were situated in Milan, Viale Brenta 29.
In 1931 the company began to produce not only radio sets but also most of the electronic components with which they were built and, over time, also developing and patenting 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.
Publications
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 above all, updates, 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.
Self-assembly kits
Another important contribution of Geloso were self-assembly kits. Theses kits enables TVs and radios to be home-assembled almost from scratch. Metal chassis were provided onto which components were fitted. There was also a user-friendlier line of pre-assembled, pre-calibrated kits and also cabinets, knobs, keys, etc. - all branded Geloso. Printed instructions explained how the finished units could be calibrated.
By 1969 - the year Giovanni Geloso died - S.p.A. Geloso had become an empire of eight factories. Production continued until 1972, when the business ceased trading. There were several reasons for this closure: fierce foreign competition, managerial problems, union demands and massive indebtedness to banks.
Some of S.p.A. Geloso most successful products were: radio receivers, tape recorders, audio amplifiers, record players, television sets, radio and TV parts, ham receivers and transmitters.
Assembly kits
Geloso's contribution to the knowledge and dissemination of radio technology was considerable, thanks mainly to the assembly kits that made it possible to build a television or radio receiver from scratch, starting with metal chassis on which the components were fitted. Other pre-assembled and calibrated kits facilitated the work.
Thanks to the instructions in the instructions, the whole set was calibrated and everything was completed with wooden cabinet, knobs, buttons, etc., all marked Geloso.
