As part of the radio frame for the Sd.Kfz.251 "Kommandofunkwagen, I was still missing a functioning power supply for the 80 Watt transmitter. I had managed to obtain two wrecks, one of which was shot through with a bullet or piece of shrapnel. Most of the hardware for the filtering of the high voltage outputs of the power supply were missing. The U80 power supply is quite unique in that it has two generators for +800V anode voltage and for -200 negative grid voltage. The rotor of the dynamotor was just touched by the bullet, the HV collector was scratched and a few of the high voltage windings were defective. Nevertheless, the dynamotor still generates a sufficient voltage to power the transmitter.
