Some brands of electrolytics have a small inductance which will cause the regulator ICs to oscillate. Use tantalum caps for C5/C6 to be sure (but also most normal electrolytics will work).
The Power supply below, it’s very simple on it’s design. There are four regulators that for us provide a variety from voltages, that probably we will need. The basic voltage are ± 15V.
The voltage of + 12V is intended basically for the circuit of VUMETER. If we do not use electronic VUMETER, we can him suppress. The himself is also in effect for the voltage of + 5V, (is intended for the input circuits, with transistor, if we do not use the zener diodes).
For until 6 input channels the regulators, it does not need they are placed in heatsinks . For more channels good it will be they are placed on heatsinks. Is good transformer T1, it is placed far by the remainder circuits.
