  We consider the possibility of creating an adiabatic transition through a
narrow neck, or point contact, between two different quantized Hall states that
have the same number of edge modes, such as \nu=1 and \nu=1/3. We apply both
the composite fermion and the Luttinger liquid formalism to analyze the
transition. We suggest that using such adiabatic junctions one could build a DC
step-up transformer, where the output voltage is higher than the input.
Difficulties standing in the way of an experimental implementation of the
adiabatic junction are addressed.
