I have been looking for similar information because my A701A only runs at max speed - the speed knob does not work.
I found the site 'howtomendit.com' useful.
One answer directed me to a Canadian site where they have some pictures of the A700 which you could copy. Not ideal but the closest I have found. The site was 'http://www.kenwoodservice.com/' or Danald's Kenwood and Bionaire Shop.
