If anyone is interested, I've traced out a schematic of the Blackface module. (newer black face plate version)
I suspect that the used module I bought was modified, and may not have correct parts. Some of the values don't match the PCB layout in the module modifications topic. (not just the 470 to 150 ohm change either)
I'd REALLY appreciate if one, or more peeps here could confirm this schematic.

Update:
Thanks to Graham for finding some wrong values, and suggesting I show which resistors are 1/2W.
The tone stack was also not drawn correctly.
The schematic has been updated.
I've already started working on tracing out my 'silverface' Deluxe module.
When it's complete, I'll work on the 'silverface' Modern module.
