These are very strangely drawn circuits, particularly the power supply that powers this power supply; in that one, the circuit seems to almost be drawn right to left, at least for the low-voltage portion (which is tapped off the high voltage portion if I read things right). This strangeness is probably - in all likelyhood - due to regional differences (east vs west schematic "standards"), plus the fact that we are dealing with power supplies, which are always messy and strange for non-trivial implementations. Also something to keep in mind here - for the 60 volt power supply that powers this high-current supply, the AC input is 230 VAC, likely at 50 Hz (ie - European AC power standard). The circuit as-is likely won't work or will work poorly, without being redesigned for the US standard wall-power (120 VAC, 60 Hz) - or even if you use the higher US standard (220-240 VAC, 60 Hz). Just something to keep in mind - that basically the initial input stage to the first power supply will need to be altered (and perhaps that weird low-voltage supply tap, too); everything after that will probably be OK, since it is DC after that point (albeit 300+ volt DC - so be careful!).
