Transformer Connection Help - Please

Hi Everyone,
http://www.cnczone.com/gallery/data/500/transformer.gif
Anyone out there up on transformer problems?
I'm busy getting all the bits together for a bench top power supply and was given a transformer out of a hi-fi set.
The problem is that it is one of those 110v - 220v types and the switch and circuit board was really busted up - wires off everywhere.
I have tested it by putting 9v (ac) into what would normally be the output side and measured what I get in other places.
The results are as follows:

Place 9v across Blue gives me:
50v across Reds
25v Red to Black

Placing 9v across Red just moves the (small, inaccurate, cheap) meter

On the other side (Normally the power input)

Pin A was wired to the one incoming line on the original setup, this was about all that I could see for sure.

Measuring the voltage from Pin A gives me:
Pin B = 75v
Pin F = 75v
Other Measurements:
Pin B to C = 75v
Pin C to F = 75v
Pin D to E = 75v

Resistances measure:
A to B circuit
A to C circuit
A to D No circuit
A to E No circuit
A to F circuit
B to C circuit
B to D No circuit
B to E No circuit
B to F circuit
C to D No circuit
C to E No circuit
C to F circuit
D to E circuit
D to F No circuit
E to F No circuit

The question is : how do I wire it up for 220v supply.
Thanks in advance for any help.
Best from the Mad Man
