I understand that a Zobel network is added at the o/p of an audio amp to retain stability into the inductive load of the loudspeaker.
A TDA2040 amp is used here to modulate a 5 watt AM transmitter. Is the load inductive enough to suggest that a Zobel network is required? I doubt it will do any harm if added, but just wondered if it *should* be added.
(L4 is about 1 mH.)
Thanks.
