SW2 presets for MC selection.
Be carefull of the polarities with + and - they are not all in the same direction. |

SW1 is used to set the load.
The easiest is to use 1 switch. SW1 1 R6 1000R SW1 2 R7 825R SW1 3 R8 475R SW1 4 R9 249R SW1 5 R10 100R SW1 6 R11 47R5 SW1 7 R12 24R9 SW1 8 R13 10R You can of course use multiple resistors to parallel them and get values in between. I wont make a chart of this. You can see the Aleph Ono user manual. Calculate yourself or use a multimeter. |

One reason I used it was that the Pearl had the same type of ground plane.

If I'm not mistaken Nelson had this because the pcb manufacturer wanted to save copper.

Solid groundplane, more copper.
