dependence on an input signal (V IN ) applied to the amplifier. 
Means (L S , S) is provided for separately supplying to said 
load (Z L ) a current (I S ) which changes at a rate faster than the 
maximum rate of change of current (I L ) in the load (Z L ) 
required by the input signal (V IN ) thereby to produce a 
corresponding change in the current (I A ) required to be 
supplied by the output stage (Q1, Q2) to the load (Z L ) in order 
to maintain the voltage across the load (Z L ) at the value 
required by said input signal (V IN ). Switching means (Q3, Q4, 
C) operated in dependence on the value of the current (I A ) 
supplied to the load (Z L ) by the output stage (Q1, Q2) causes 
the sense in which said changing current (I S ) changes to 
reverse when said current (I A ) supplied by said output stage 
(Q1, Q2) exceeds a predetermined positive value (I AP ) or a 
predetermined negative value (I AN ) which predetermined 
values are less than the total current (I L ) required by the input 
signal (V IN ) to be supplied to the load (Z L ), thereby to restrict 
the current (I A ) supplied to the load (Z L ) by the output stage 
Q1, Q2) to values between said predetermined values (I AP , 
 AN ).  
     The means for separately supplying a current to the load 
suitably comprises an inductance (L S ) connected in series 
with a voltage source (S) across the load (Z L ).
