In this section, I gather a series of articles that I consider interesting and useful for the in-depth exploration and understanding of various topics. Since the website is newly created and there isn’t yet a great variety of articles, I don’t think it’s necessary to organize their list in any particular way.
Bollettini geloso
The Geloso bulletins are a valuable technical resource for those who intend to repair or restore the various devices produced by this company.
The first bulletin was released in 1932 at the will of John Geloso himself, continuing until 1972 when the regular releases ended, and the bulletins started to become sought after and soon became collector's items.
The purpose of these documents was to promote the quality of their equipment while, at the same time, providing useful information to repairers and technicians who requested it. Here, you can find circuit diagrams, notes, and advice for proper usage, as well as often general insights.
Thanks to the enormous work of Paolo Califano (IW2DGS), it is available on the website geloso.net l’intera collezione dei bollettini Geloso digitalizata in alta risoluzione e liberamente consultabile.
Dopo uno scambio di mail con il sig. Ezio Di Chiaro, uno dei fondatori del sito citato, ho ricevuto l’autorizzazione a linkare il loro sito internet completamente dedicato alla Geloso e che consiglio di visionare.
