Heathkit PS-4 Power Supply--Manual Available?

[N2IXK]

I just got a Heathkit PS-4 regulated 0-400V power supply that is nonfunctional, and the assembly work is pretty atrocious. I am thinking that this unit is a good candidate for a "rekitting" and reassembly.

Unfortunately, I didn't get the original assembly manual, and can't seem to find one on the web anywhere. I can only find the schematic, which is helpful for troubleshooting, but I really need the complete manual to do a rebuild. Does anyone have access to a copy they can scan and share?
