I never read ETI so can't comment on whether they used this terminology or not but I remember it from the early issues of Elektor ...
For the benefit of anyone who hasn't encountered these terms before, they stand for Transistor, Universal, PNP (or NPN)
See www.sentex.ca/~mec1995/circ/tuptun/tuptun.htm for more.
Quite correct terry, I can't even blame that one on a typo.
Must engage brain before using keyboard. Regards. Andy.
