kenwood ka-52/72b amplifier service manual

i looking for a service manual for a kenwood amplifier model # ka-52b. in my endeavors i have found that the model ka-72 is also listed in the owner's manual, and thus a service manual alternatively for this model would, i believe, serve my purpose as they are identical except for the final output stage (100 w as opposed to my 50 w). if anyone can post or send me a copy personally to my email address (collectiques4u@hotmail.com), i would greatly appreciate.
