I had an RF103 that I parted out 4yrs back, as a feral cat have lived inside the box and urinated all over, and corroded some of the metal. The innards all made good parts for other amplifiers, however. What I need for the 101 is how the tuning memories are done, and details like that. I found a ham here who is sending me a copy, thanks all. 73 John K5PRO
