[Milsurplus] Selenium rectifier pin-out help needed

[Laura and Jim]

I have a 4 plate (3" diam.) one in a mains PSU for my TCS-8 I need to replace because it runs warm and is becoming smelly..........

Picture this if you can:

One connector on each end of the stack, one connector between each plate (five total). Outer ones are tied together. Four wires in/out.

If I use a modern replacement bridge, which wires (AC, + and -) go where? 

Can't seem to find a diagram on-line showing this. I have seen other Se rectifiers w/many more plates (for higher voltage rating?) These are even more complex.......

I understand there's a voltage drop per junction I will need to compensate for in order to keep the output voltage at it's original value.

Thanks for the help.
