The ultra-regulation of the power supply +48VDC,+24VDC,+16.4VDC is so over the top and unnecessary that most, if not all, people building this amplifier would not even notice the difference. However there are a number of benefits to this design. First its a dual tracking design. Because the open loop gain of the amp is low, [...]
The dual rail supply which means there are two supply voltages, one positive, one negative, that are adjusted by a common potentiometer such that supply voltages are equal in magnitude. It is capable of supplying up to +/- 15V DC at up to 1A.
Two linear regulators are used, an LM317 on the positive side and [...]
