I just noticed that this power supply is for the 12W amplifiers thread.
Audio amplifiers do not use and do not need a voltage regulator.
The amplifiers produce hum maybe because their input bias has absolutely no filtering.
Instead of using a high current voltage regulator to reduce the hum I recommended and showed a simple RC filter for the input bias to reduce the hum.
