History: |
DeForest Radios suffered from the lack of regeneration. An Armstrong license was urgently needed. We put all Radio Craft models (which are extremely scarce) together with the Deforest listings. Often there are problems to distinguish, since for a short time DeForest even offered regenerative models under their name (in contempt of court judgement!). Such panels were discovered on the DeForest side of the factory.
