Front End Control Troubleshooting
A15 Front End Control Assembly Troubleshooting
Even if the voltages listed in the table are correct it does not guarantee the
proper control current is getting to the YTF. There is not a convenient way to
measure the control current, so if a high band issue is suspect it is
recommended that the A15 is changed out first before changing the YTF since
the A15 board has easy access.
