The Zenith Radio Coy. advertised in September 1933 for dealers to handle lines of complete receivers and chassis in the suburbs of Sydney.[1] Jose Alberti became associated with radio when he founded Acorn Pressed Metal Co. Ltd. and manufactured radio metal parts and chassis in 1931. [2] The company started manufacturing in Paddington and advertised in the Radio Trade Annual (RTA)1933 as “Specialising in Component and Receiver Construction for the trade”.[4] In the RTA 1934 edition they are listed in the Manufacturers Directory and the Buyers Guide as suppliers of chassis, chokes, capacitors, receivers wired and complete. In February, 1943 they took over the production of "Calstan" brand radios and test equipment from Slade Radio Pty. Ltd. After the war their address was 121-123 Palmer St, Sydney by which time they had become Zenith Radio Co. Pty Ltd. By the late 1950s they were manufacturing televisions and their address was 7-11 Rhodes St, West Ryde, Sydney. Production ceased sometime in the 1960s. According to Mingay’s Radio Diagram & IF Index, 1933-39, Page 95, Zenith Radio Co. manufactured 15 Ambassador brand radios in 1937. This has not been confirmed by actual models found or other references to date.
