I have the service manual as well – the SPARC radio museum, in Coquitlam, has a set. I’m in the slow process of restoring it for display, being a local manufacturer. I would really like to know about the company, they didn’t seem to be in existance for very long. RCC doesn’t mention them so its great to have the actual service manual ( with the tech’s personal notes scribbled in the margins ). I think the design was based on the U.S. Setchell Carlson chassis, which was also unitized, so possibly they had the license to manufacture in Canada. I have a personal attachment. It was the first TV the family had. Fond memories of going to the drug store to test the tubes – which seemed to be quite often ! thanks for the response.
