The "official" aircraft inverter for the GO-9 was the 800-1.  See https://aafradio.org/flightdeck/go9.html for the details.  The Navy would never use a Signal Corps inverter for its equipment.  It might get Army cooties.  🙂

Just teasing, of course.  The Signal Corps did provide a PU-43-A version of the Navy standard mentioned above, but the one I had appeared to be simply a label switch on the same inverter that the Navy used.

And yes Ken, you're right, the supply was 800HZ, 120VAC for both the TBW and the GO-9. The  The supply had various values of switched capacitors to match the dynamotor, which I believe was a PE-103A or a PE-3 for the GO, just not sure of the designator. For the TBW it was a gas powered 800HZ 120VAC.  The TBW was normally supplied in 3 water-tight cases, the GO is not, each section connects to the others.
