From the date, you probably have the original Paramour; the earliest draft of the Paramour II manual that I have seems to be dated September 2006. There should be a paper manual 5.5" by 8.5" and dated 2000. The output transformer would be labelled "50-130" and the chassis plate would be 6" by 10".
Assuming that description matches what you have, one side of the output transformer will have three wires, labelled C (black wire), 4 ohm (yellow), and 8 ohm (white). The black goes to terminal 22, one of the others goes to terminal 24, and the remaining wire is loose with the end covered by a bit of heat-shrink. Terminal 22 is connected to the black binding post, terminal 24 to the red post. You can swap the yellow and white wires to change the impedance.
There was an iron upgrade kit with different plate chokes and output transformers, so if the above description does not match, better post a picture.
