Hello to the group Thought I'd make another semi annual appeal for these gas powered generators to finish up two of my field sets. The PE-108 is a 120 vac generator that was used to power the BC 669 . The PE-49 is a 1kv dc and 12 vdc generator used to power the BC 191 as used in the SCR 177 field configured set. Tnx Paul N6FEG
