I opened a Sider to take a look and realized I have a spare duplicate
power supply in my parts cupboard. The only difference is that instead
of soldering the wires directly on, they used connectors instead.
The power supply is an astec. Not sure of the part number. I just
uploaded a pic to

The pic is called astec_ps.jpg. If this is the same as yours you can
have it for the cost of shipping from Canada.
