It didnt even take me an hour to draw up a schematic for BOTH amp section and psu for a P2P MPX3. There are wires going every which way, agreed, but they all go pretty directly to what they go to. FWIW, in all 3 of the SP toasters I have looked inside of, about 1/2 of the wires are there to hook something to the star-ground point. I suppose Mikhail could have used a ground bus, but there are lots of other compromises he could have made too.
There are only a few realistic topologies for an OTL tube amp. When you take the "only class-A" philosophy of SP you eliminate a couple which are capable of running class-AB and still sounding OK. Then the biggest thing separating the men from the boys is the power supply. A good power supply means a LOT to a tube amp (and many SS amps to a lesser degree too.)

If it is an issue of something rattling loose, it will be a simple visual check, and then repair.
