I'm trying to find the '3.9uf 35v Bi Polar: D=18mm, H=35mm' for the Macintosh Plus International version as listed above.

Are there any similar caps I can use instead that's easier to find? Preferably from futurlec: http://www.futurlec.com/cgi-bin/search/searchold.cgi?Q=3.9uf&E=1&X=0

And this one: 474K, 400V Metal Poly: L=23mm

Is that a resistor or what? a 400 voltage capable 475 kOhm resistor?
