Can anyone tell me what the value of the Zener Diode D203, WZ060 is, it 
is mounted on the PB-2117 PC Board in the FP107 power supply. It appears 
to be identical to the power supply used in my FT-one, and I believe the 
Zener is faulty, but I have no voltage characteristics etc to go by to 
get a replacement.
I would also like to express my appreciation to Art K5FNQ for his help, 
especially for obtaining the circuit diagram of the power supply which 
my FT-one Workshop Manual did not have.
