signal portions and other sensitive circuits for the best performance. For an audio power amplifier, regulated supplies need high bandwidth for good audio performance. The complexity and cost for such a power supply design may not be acceptable. Most linear regulator ICs do not have high bandwidth and

The GT-102 has an electronically regulated power supply. That makes it unusual among audio power amplifers. But in some ways, it offers an advantage similar to class A operation. Class A amplifiers can be among the most linear of amplifiers, and the least efficient. They draw a constant current from the power supply, no matter what signal is being delivered …

A regulated supply-rail voltage means that the amplifier can be made to approximate more closely to a perfect voltage source, which would give twice the power into 4 O than it gives into 8 O. This is considered to have marketing advantages in some circles, though it is not clear why you would want to operate an amplifier on the verge of clipping.

27/04/2018 RAJ SHARMA. The power supply has been designed to use for audio power amplifiers. This power supply uses a transformer, a bridge rectifier, various rail capacitors, fuse for protection, also supply has separate dual regulators for +/-15 V DC output. Maximum output for main audio amplifier +/-42V DC, high voltage output possible by altering bus …
Amplifiers: Power supply - Lenard Audio

However because an amplifier can not be driven with music greater than 1/3 of its capacity with a sine wave the size of a power supply does not need to be greater than its full power rating into a speaker. A very large power supply has better + - V rail supply regulation. The only disadvantage of a large power supply is mass.

A regulated amplifier power supply tries to maintain a steady output voltage. As the input supply voltage sags it will try to draw an increasing amount of current. As many of us know, it gets expensive to increase the current supply(high output alternator, large gauge wire, etc.).
