Repairing Apple II power supply

I am attempting to repair an original A2M001 style power supply (not made by Astec) for my Apple II. I need the Bill of Materials and component layout drawing to determine some the values of several burnt resistors. Does this documentation exist?
I have the schematic (from the 1979 Apple II reference manual) but it does not show component values. The power supply board does not have component references silkscreened on it.

This is a genuine A2M001

This is a genuine A2M001 supply. The case is silver colored, brushed aluminum with a red/white label that says "POWER SUPPLY SERIAL # A2M001 - 34266. It has a date of Feb 21,1979 stamped on the lid. I reverse engineered most of the primary section to confirm that it does match the schematic in the 1979 reference manual. I am looking for the resistor values.
The power supply opened up looks similar to this https://imgur.com/a/DY67W/

This information is for Astec model AA11040

This information is for the power supply made by Astec Components model #AA11040. The front end is considerably different to the Apple power supply model A2M001. Hence, I can't make use of this info. I added a link in previous comment of what the A2M001 looks like inside.

Resistors are burnt

Unfortunately, some of the resistors were badly torched and are not shown in the image link. Since this power supply was installed in an Apple II, A2S1 - 20278, Apple must have made quite a few of them. Apple has a US Patent #4130862 on this supply which details how it works and schematic, but no component values. I also reviewed pages 170,171 of Level II Service Manual, but no values listed. I am hoping that a parts list exists somewhere...
