Page 4: Building Sequence
Magnum v1.0 Building sequence Soldering this board can be very complicated for some people since the solder pads are very close together. Use a magnifying glass to make the job easier. First decide which charge pump you want to use. IC2 can fit a LT1054 or even the cheaper ICL7660S. -

Magnum v1.0 Modifications Diodes and Op amp You can use other diodes than the mentioned combinations. Try LED’s, MA858/859 (very nice!!), D9E, etc. D1-D4 best fit the bigger glass germanium diodes. D5-D8 best fit the smaller silicon diodes. IC1 can be any dual op amp of your liking. Try the JRC4558, JRC4559, AD712, MC1458, TL072, OPA2134, OP275, etc, etc. -
Page 6: Off Board Wiring
Magnum v1.0 Off board wiring The biggest challenge of this build is to get all the offboard wiring correct and fit it in a box. Take your time measuring and testing before you start fitting everything in the box. P1-P4 are PCB mounted potentiometers (Alpha). The rectangle pad marks pin 1 of a potentiometer. -
