Exactly: that's the question I was encouraging the TS to answer for himself. Transformers, even audio transformers with extended low-frequency bandwidth are relatively efficent.I see nothing that makes a transformer-coupled amplifier less efficient than a direct-coupled amplifier except the tiny amount of heating in the resistances of the transformers that wastes a small amount of power.
What a coincidence. My first job was as a technician on the Philips car radios production line. The latest one used AD161 and AD162 germanium complementary output transistors. It was spec'd at 4W into 8 ohms so instead of using bridged amplifiers, it used little output transformers to step-up the output signal voltage.Probably he meant to specify AD161/AD162
Yes, but i think it is intend to get a crossover distorted signal in output, as it is class-B.Hi a
Checked your Fi5, severe cross over distortion, try a 0.68v input signal ie: 10%.
