    The Society for the Preservation of Antique Radio in Canada (‘SPARC’) located in Coquitlam, BC, are in the process of revamping their website ( and CVRS members are encouraged to take a look. The site now features a ‘virtual tour’ and a ‘projects’ section, the latter including a feature on Chisholm Industries Ltd (it is planned to include some of the elusive Chisholm schematics in the near future). There are more pages in the pipeline, incuding one on tubes and the role Rogers had in the development of the ‘AC tube’ in the 1920’s – so keep popping back for a visit.
