A severe thunderstorm ran through the Dallas area in the wee hours of Monday morning.  One of the casualties was my rotor control box along with the computer it was connected to via serial cable. 

It looks like the damage is limited to the upper control board.  The schematic on Yaesu's web site is unreadable.  Can someone give me the values for Q1001, Q1038 and D1001?  D1001 appears to be a small bridge rectifier.  If I can fix this for a few dollars in parts it would be great since Yaesu sells the power supply board and the control board as a pair for $340.96.

I can read my schematic.

Q1001 - UPC7808AHF - That appears tp be a 3 terminal 8 volt regulator
Q1038 - UPC7812AHF - That appears to be a 3 terminal 12 volt regulator
D1001 - WO2G - I'm not familiar with that number but it is a bridge rectifier.  Most anything with the same pin-out should work.

I sent a copy of the schematic for the G-2800DXA to your email address listed on QRZ.  I think you can read this one.
