[Milsurplus] TADDS Receiver schematic

[Dave]

G'day all,

I have a small VHF receiver which was originally part of the Target 
Alert Data Display Set, AN/GSQ-137 (XO-2) (Forward Area Alerting Radar 
System).

A previous owner apparently applied 24v to it instead of its intended 
12v. Needless to say, it doesn't work so I'm looking for a schematic 
diagram in an attempt to track down possible faults.

The user manual was apparently TM 9-1430-589-12. Were there any 
maintenance manuals issued?

Thanks and cheers
Dave
