I just picked up a cool vintage (circa 1985) electronic load off ebay (Kikusui brand), and am looking to replace its cooling fan. The original is Minebea 2415PS-10W-B30 100VAC fan. The company seems to now be a part of NMB, but the 100VAC version is nowhere to be found in stock. Their 115VAC version though is easily obtainable. Hence is my question- what happens when you run a 115VAC rated fan off 100VAC? The load powers it off a separate winding on the mains transformer. I realize I could feed it off mains, but would rather not mess with the original wiring.
Load teardown pictures are coming up in a separate thread;)
