zuiko21 wrote me a PM to say that the schematic he used to see the 4.7-ohm resistance is found in two separate files here (names "Analog Board" 1 & 2):
http://www.ccadams.org/se/pinouts.html
But being one who absolutely hates hard-to-read schematics, I took it upon myself to combine, clean and straighten those awfully scanned documents. The resulting PDF is formatting for printing on B4 paper at 244dpi:

True, some text is still blotchy and hard to read, but that is the fault of the original scanner. But I must say this single PDF is much more useful than the original two GIF scans.
Even so, I have not yet confirmed the content of this schematic. The user should therefore take its content with a word of caution, carefully checking your actual analog boards with this schematic to see if it matches. And more to topic, SE/30 owners should check if there is indeed an R31 sized 4.7k-ohm sitting between the positive line of your Elina fan and +12v power. I am unable to do that right now, but I intend to check it when I find the time (which may be some days from now).
