power supply question

In getting ready for my new gecko 201's to arrive I need to prepare a
power supply.

Here is what I have:
28 VAC at 4 amps output supply transformer (~100VA)
rectron mp-15 400v 15 amp 1 phase bride rectifier
10000 microfarad capacitor - computer quality

28 Vac input * 1.41 = 39.2 VDC output

The tech guy at gecko he gave me the specs on the bridge rectifier
and cap.

How do I wire the rectifier? It has a AC terminal and a plus
terminal with two unmarked terminals.

I assume the AC input L1 should go to the AC terminal and the nuetral
to obe of the other ones but not sure which. Then pick up the +DC
output from the plus terminal and the common from the other.

I checked the Rectron website and did not find any wiring diagram.

Any info would be greatly appreciated.
