Description
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.
