[Elecraft] 4-ohm to 8-ohm question

Eddy, the transformers were made tor tube type amplifiers where the output was several thousand ohms and transforming was needed.  Some audiophiles still use tube amplifiers for mellow sounds from music, but the transistor output stages match either 4 or 8 ohm speakers directly and are fine for communications audio or ordinary tone deaf  listeners for music. Willis 'Cookie' Cooke,

Not necessary because today's audio amplifier designs do not require
matched impedances.  You are "good to go" with no further matching.
