Where purchased: eBay, July 2004
I found the circuit diagram in the RCC manuals and in Rider's. There was a version with loctal tubes; the chassis has both octal and loctal tube numbers stamped on it.
On the back is a sticker than says "WHYNOTT'S TV-RADIO 543-3101". This is likely the shop that originally sold the radio. I thought with a little detective work I could possibly track down it's location. The seller of the radio on eBay was from Ingramport, Nova Scotia. I found there is a 543 phone exchange in Bridgewater Nova Scotia, so it may have been located there (the area code would be 902). A directory search found 9 people with the surname Whynott in Bridgewater, NS. Bridegwate has a population of only 7800, so 9 names seems to imply it is a common surname there. By contrast, the city of Ottawa only listed one Whynott in the phone directory from a population of almost 900,000. A reverse phone lookup did find a residential phone with this number in Bridgeport NS, however the name was not Whynott. Since this radio was made in the 1940s it is likely that the phone number was reallocated.
As received it was not working and had some problems: a tube was missing and another was marked "BAD". A knob was missing and the other was partially broken. The line cord was brittle and missing insulation, the back was badly warped, and the chassis was loose.
Someone had worked on the radio at some point. Some of the caps didn't look original, the speaker was repaired with glue, and the back was held in place with a wooden block that didn't look original.
After replacing two tubes, the line cord, the wax caps and one bad resistor, the radio worked. I gave it a good overall cleaning and polished the case. The only visible problem remaining is a missing knob.
