Section 3: Power Supply Board Construction
Here are the parts for the Power Supply Board along with
the spacer hardware.
Quantity Description
4 1,000v 3A fast Diodes
2 220uF 450v Electrolytic Capacitors
1 330K 1W resistor
2 1M5 1W resistor
Installing the Components
IMPORTANT: The Diodes that we are
using have a stripe on one side that
you need to match with the PCB. They
must not be inserted the wrong way
around.
Bend the leads so that they can be
inserted into the PCB.
Next, install the 3 resistors.
Note that the board shown in the picture was a Beta board
with wrong stencil markings but as you can see the 330K
resistor is at the bottom of the board and the 2 x 1.5M are
above it.
