[ICOM] 756 ProII low power

[Bruce]

Just a guess but check the diode and transistor on the tuner control 
unit, those components are in the T/R circuit..measure the resistance 
across the diode, it should be about 9K ohms. If it is less then that 
diode and transistor are shorted, check the resistors in that area 
too. Next go to the RF unit and check all the diodes that switch RF 
between Rx and Tx..you may even have some shorted in the BPF section too.
