- Notes
- "Ultradyne LR4 is the radio model for which Robert E. Lacault invented the circuit Ultradyne." There is some doubt in this model LR4, since the first kit had no name, and a price of 137 $ for a kit is not realistic . The kit (no further name) was offered e.g. in Oct.1924 for 26 $! This model LR4 is certainly a complete improved table model. "Kit" seems to be an error in Radio Coll.Guide 1921-1932. Lacault named some of his models also Strobodyne.
