Hi Pete,
Unfortunately, my machine doesn't seem to match the descriptions
in your last message. The silkscreen definitely says "Sorcerer II".
In terms of the power supply... There is no black/red wire
on my transformer. All of the wires are on one side of the
transformer (away from the filter). There are 11 wires:
Solid black- NC
Solid yellow - NC
Black with yellow stripe - line filter (LOAD)
Solid white - line filter (LOAD)
Black with white stripe---\
}Connected together
White with black stripe---/
My guess is that those are the primary winding connections.
The 'LOAD' side of the mains filter is the output side (meaning it should
be connected to the laod) and is effectively the mains supply to the
transdormer. My guess (again, I've not seen this machiue) is that there
are 2 primary windings each of 115V or so) and theey'r currenyl conencted
in series fro 230V (or so) mains. Whether the totally unconnected wires
are also taps on the primary windigns (it wasn't uncommon to have
0-100-120V windings so you could wire them up for 100V, 120V, 220V or
240V mains) I don't know, but it probably doesn't matter.
What you need to do is to open that connection between the Black/White
and White/Black wires. Then test the ends of these wires to the loadf
terminals of the line filter (do each wire separately, and leave the 2
transformer wires connected to the line filter). You should find that
each fo the 2 'free' wires tests with a low resistane to one terminal and
infinite resistance to the other one. Then connect each of the 'free'
wires to the terminal it tested as infinite resistance to (if you work
out what's going on, you'll see this connects the 2 primary windings in
parallel, with the correct pahising)
Then test the supply on dummy load!
