Circuit Project Electronic

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 [...]

Bench DC Power Supply - Assembled
This is a practical bench power supply for all your projects. It has three fully regulated DC supply outputs. Two outputs are continuously variable and one is fixed.
Specifications:
* Output Voltage: 1) 1.5VDC - 15VDC @ 1Amp, 2) -1.5VDC to -15VDC, 3) 5VDC @ 3 Amps.
* Input: 110VAC (line [...]
