    I am embarking on my first restoration. I recently acquired a Sparton model 10140. It’s a BEAUTIFUL 10-tube console that was manufactured in London, Ontario. This is rather significant to me since I live just outside London. I’m having difficulty locating a schematic or wiring diagram. Since this is my first restoration, I decided to join CVRS in hope I may find some assistance with this, and network with others so I may be able to give something back to the community in the future.

    Can anybody tell me how I might track down a schematic for a Sparton 10140?

    Thank you,
    ~ Brian

    Hi Brian
    I just noticed that yours was not the red radio in right side of page.

    Although the red one on the right was in fact a Sparton Polo, no, mine is the large wooden console pictured in my message above. It’s a beautiful cabinet. I need to have somebody look at it who’s more familiar with wood than I am… I’m thinking it MAY be Mahogany. Then again, since it’s manufactured in London, probably Maple….

    Thanks for the reply.

    I don’t see a 10140 but you might try to open a few of the schematics to see if you see similarities in the tube lineup.

    also look search under Sparks-Withington Co.

    Sparton made at least some of their own tubes. I had one with output tubes that were similar to 45’s but with a different heater voltage,and it was a bit hard to find. There was a workaround to re-wiire the heaters in series to accept 45’s instead. It looks newer than a model that would use 45’s but you never know.

    Hi Brian – I still have an original Sparton 1040 I bought when I was 15 yrs old in Colborne, Ontario. I pulled the schematic from a CD called Canadian Radio Circuits- 1938 t0 1948, data base Volume 2- that I bought a few years ago. You might also google it and the CD may still be available – it wasn’t very expensive. See if you can open the attachment Sparton 89 as it is the schematic of the 10140 from the disc.

    Re the 10140 cabinet Brian the wood veneer is walnut for all surfaces except those base parts which are lacquer toned darker. That wood is usually a light Elder to start with before factory finish applications.
