Show three circuit beat of regenerative hookups hook ups the three circuit set la Is by far the best of the regenerative hookups hook ups this circuit employs a three coll coil coupler or tuning unit one of these Is the primary or antenna coll coil one to la the secondary and the othur Is the tickler coll coil there are any number of very efficient units of this type on the C 4 M 4 M j do 4 I 1 0 W r IN X of III three curant regenerative hookup market and we rc commend them very I 1 highly I 1 aly this Is the best of the regenerative live circuits because it tunes sharply and gives good signal strength and do does not send ont the strong interfering wave when set into oscillation as does the single circuit or the ultra audion the diagram shows all of the instruments that tire are required it is important that the capacity of the con condenser demer should be that recommended by the maker of the tuner to be used |
