I cannot believe that Bob Fitzgerald would have the knowledge to create an SMD design, so I suspect the PCB is probably salvaged from some other piece of equipment, and "adapted" to look like something that might actually work. Which would explain why Carl's schematic and your particular device do not tie up. In fact, I'd be very much surprised if any of these devices look anything like each other, unless Bob Fitz got hold of a job lot of surplus junk.
