I bought a 478 a month ago that works great, but the Hit Tracker is dead.    
   Each of the song-tracking 4 displays have a burn-out point on the board,   
   leading me to believe - the root cause is the power supply.   
   I have the service manual but it does seem to have voltage test- points.  Is   
   there a document that has them, so can test the PS, before getting and   
   plugging in a replacement Hit Tracker?   
   Thanks!  Dale
