Power Supplies
The line voltage is filtered and applied to the main power supply, a 15 V supply that is always on when line power is
applied. A regulator creates an earth referenced +3.3 V supply from the main supply, and this is also always active
when line power is applied.
A small microprocessor on the main board senses the power switch and enables all other supplies.
