Does anyone have the PDF for the Plitron 4142 ?

Hey

Trying to finish up a very OLD project that has been collecting dust since i left the hobby. Its a Williamson amp based on the Plitron 4142. The problem is my schematic the OPT is numbered, but I have no clue what colour wire is what number. The amp is basically finished but I want to double check everything. And if these colour wires are swapped my NFB becomes PFB.

Thanks for any help you guys can provide.
