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.
