Craig, back in my days in college in electrical engineering , electron flow was from neg to pos, and current flow was from pos to neg . In radio tubes the cathode is the emmiter and the plate is the collector , the plate is pos charged and hence the electron flow from neg to pos . But all electrical theory is based on the fact that current flows from pos to neg . Seems like the electrical world is about as organized as a soup sandwich . Maybe it has changed since I got my degree in the early 60's . george
