regulated linear power supply module
2 independent and adjustable power circuits
Specific audio components
Each power supply circuit operates with a MJE15034 transistor, a BAOTER controller 3296 and a TL072 operational amplifier.
Double adjustable voltage circuit
This double supply circuit is used to select a different voltage to each circuit with a solder connecting point of the resistances therebetween. Resistance H (high) in 33km, M (medium) 12-18K and L (low) 3K3-6K8
To obtain an output voltage between 20 and 28 V (supply of discrete circuits), the High position is indicated
To obtain an output voltage between 12 and 18V (preamplifier) it will be necessary to also connect the resistance M
Finally to achieve a voltage of between 5 and 9 volts (for supplying a DAC, for example), it will suffice to also connect the last diode (L).
By default, the resistors H and M are connected. The unpacking the output voltage will be of 12-18V
independent outputs & joint
Both terminals can be used séparéments or jointly.
Separately, they constitute two separate and independent outputs. This will get 5V to 9V left and right.
If necessary, it is possible to connect together the two terminals GND in order to obtain an output positive (VCC) and negative (VSS)
