Page 5: Power Section
Heavenly Red v1.0 Power section IC1 can be either a LT1054 or a (cheaper) ICL7660S. I do not advise the use of a battery in this build as the charge pumps will do strange things when the battery is depleted. This is why it is also left out in the off board wiring section. -
Page 6: Off Board Wiring
Heavenly Red v1.0 Now continue by soldering the MLCC, small SMF/MKT/Wima capacitors then solder the internal trim pots (VR1-VR4). Now finish by soldering the transistors (if not socketed), the bigger MKT/WIMA and the electrolytic capacitors. I suggest you now drill the holes in your enclosure so you can use it during the off board wiring. This PCB is very sensitive to noise! Keep the wires as short as possible and/or use shielding on the input and output. -

Page 9: Modifications
Heavenly Red v1.0 Modifications Structure The original only has a structure on-off. In this version I added an extra option for a second structure option formed by C16a and R13a. After some experimenting I found the 1uF/15k combination to have some added value, but feel free to experiment and let me know if you found a good combination. -
