it has a very small gap between the opening of " E " sharp,it uses special steel alloy plates rather than pure steel plate use on ordinary  power transformer.

Answer 2

they are designed for a different freq range

Answer 3

An audio transformer is designed to be operated within the audio range, usually about 20Hz to 20kHz.  The manufacture of the core determines its frequency range.

A 'normal' transformer is intended for connection to the mains, so the core is manufactured from iron and will operate at low frequencies.

Answer 4

An audio transformer is a normal transformer with an MP3 player built in.  I think they sell them in Argos.
