Description

Positive and negative voltage regulator PSU made with 78XX and 79XX series voltage regulators.

 

The scope of the project is to provide clean -15V, GND and +15V to audio circuits. 

 

I created this for 44090 series Myrra transformers.

 

Optional JST connector for a small 12V fan "P1"

 

31th Aug 2023:

 

Corrected capacitor polarity placement and revised to v2.0b.
