Look again:
http://www.nostalgiaair.org/Resources/881/M0013881.htm
Scroll down the several pages...they do have the schematic for the 1-47 version of the 90 in there.
Or if you get bored, you can always look here:

You can use 600 or 630 volt caps to replace the caps inside the bakelite block shells; 450V is fine for the electrolytics.
