Here is a three tube reflex set with two stages ofR.F. amplification and two stages of A.F. amplification which arecontrolled by jacks. One jack is used for plugging in a loop whendesired while the others provide means for plugging the headphonesor loud speaker in the successive stages of amplification.I .000sLoop 900,9k ifkfenbome/e,DA.

It issimilar to those of the reflex type except that the work is evenlydistributed between the three tubes so that none of them are overloaded.The paths for the radio frequency currents are madeshorter than in the usual reflex set. The Inverse Duplex receivershown here has two stages of R.F. amplification and two stagesof A.F. amplification. Standard transformers may be used.39
