Overview
Telsen Electric Company Ltd was a British electronics and electrical-appliance business associated first with Birmingham and later with Manchester. Established in 1924 by A. Macnamara at 207 Aston Road, Birmingham, the company operated during the formative period of British domestic radio, when households could purchase either complete wireless receivers or the components and instructions needed to build sets themselves. The company initially developed a broad product and manufacturing model. It made wireless broadcast receivers, radio components and construction kits, while also maintaining a cabinet-making department that produced polished furniture cabinets into which receivers were installed. Some cabinets were purchased from Birmingham manufacturer Edwin Elliot, including Bakelite cases. Telsen's range was intended to cover much of the equipment required by amateur constructors, rather than focusing solely on finished consumer radios. The company also supplied blueprint layouts designed to help customers assemble receivers neatly and consistently according to Telsen designs. In 1930, the business moved from Aston Road to 56 Miller Street in Birmingham and subsequently relocated to a factory at the junction of Philips Street and Thomas Street. The company was formally incorporated in 1933. Around 1933 or 1934, it supported its component and construction-kit business through Telsen Radiomag, a Birmingham-published magazine associated with James Cond Publishers. The periodical appears to have been irregularly issued and completed six known issues of its first volume. Its contents included product information and, in later larger-format issues, loose blueprint sheets. The publication reflected Telsen's effort to combine hardware sales with practical guidance for radio constructors. By December 1934, Telsen had insufficient assets to meet its creditors and entered liquidation. In 1935, David Rosenfield Ltd acquired the business out of receivership and moved operations to Manchester. Under the name The Telsen Electric Co. (1935) Ltd, the business broadened its output beyond radio equipment. Products associated with the Manchester period included clothes irons, toasters, Christmas bubble lights and fairy lights. These later items are principally encountered today through historical collections and auction listings rather than through an active retail operation. The original Aston premises have since been reused. The former factory site became The Telsen Centre, a managed-workspace facility operated by Midlands Industrial Association Ltd, a community benefit society serving new and small businesses. This later use is separate from the defunct manufacturing company but preserves a connection to the site of Telsen's early industrial activity. No evidence in the supplied reference material indicates that the Telsen business remains active, has a current corporate website, or continues to market products under the brand.
History
Telsen Electric Company was formed in Birmingham in 1924 by A. Macnamara at 207 Aston Road. Its early business reflected the rapid growth of domestic wireless in Britain. Rather than limiting itself to completed radio sets, Telsen manufactured receivers, individual components and construction kits for customers who wanted to build wireless equipment at home. The company also prepared blueprint layouts intended to guide orderly construction using Telsen designs. The company combined electronics manufacturing with furniture production. Its cabinet-making department produced polished wooden cabinets into which radio receivers could be fitted, while some Bakelite cases were sourced from Edwin Elliot, a Birmingham supplier. This combination allowed Telsen to sell both the technical apparatus and the finished domestic form in which it would be used. In 1930, Telsen moved to 56 Miller Street. It later established a factory at the corner of Philips Street and Thomas Street. The business was incorporated in 1933, by which point its catalogue covered the components needed for home radio construction. The catalogue material was subsequently associated with Telsen Radiomag, a magazine published in Birmingham by James Cond Publishers. The magazine appears to have been issued around 1933 or 1934 and to have run for six issues in its first volume. Publication was irregular; the format expanded after the second issue, and later issues included loose blueprint sheets. The periodical served as a combination of product catalogue, construction aid and promotional publication for the Telsen system. The company encountered financial difficulty soon afterward. By December 1934, it lacked sufficient assets to pay creditors and was liquidated. In 1935, David Rosenfield Ltd acquired the business from receivership and transferred it to Manchester. The successor operation traded as The Telsen Electric Co. (1935) Ltd from premises on Fitzgeorge Street, Rochdale Road, Manchester 9. The Manchester business broadened its product range beyond wireless equipment. Products attributed to this phase included clothes irons, toasters, Christmas bubble lights and fairy lights. Examples of these goods continue to appear in auction markets and collecting contexts, but the supplied sources do not establish a continuing corporate operation or a precise closure date for the successor company. The historical Telsen factory in Aston has since been converted into The Telsen Centre, a managed-workspace development operated by Midlands Industrial Association Ltd. That reuse gives the former industrial site a continuing community and business function, although it is not evidence that Telsen itself remains active.

Some receivers were installed in polished cabinets made by the company's own cabinet department, creating finished furniture-style products for household use. The available reference does not identify particular model names or technical specifications.
Radio components
Radio components and construction kits
The Birmingham company supplied components intended to cover much of what a home constructor needed to build a wireless receiver. Telsen also sold construction kits and provided blueprint layouts to encourage tidy assembly according to its designs. This system connected component sales with practical guidance for amateur radio builders.

Telsen Radiomag
Telsen Radiomag was a Birmingham-published periodical associated with Telsen's radio business. Its first volume is reported to have comprised six issues, published irregularly around 1933 or 1934. Later issues used a larger format and included loose blueprint sheets, reinforcing the magazine's role as both a product catalogue and a guide for home radio construction.

Electrical appliances
After David Rosenfield Ltd acquired the business and moved it to Manchester in 1935, the Telsen operation produced household electrical appliances including clothes irons and toasters. The supplied material does not provide model details, production volumes or a definitive end date for these lines.
Seasonal electrical lighting · 1935
Christmas bubble lights and fairy lights
The Manchester-period business also made seasonal electrical products, notably Christmas bubble lights and fairy lights. Surviving examples are encountered in auction and collecting markets, providing material evidence of Telsen's shift from radio equipment into decorative consumer electrical goods.
