To be honest....?how do I know which pins are top and which are bottom?


You have the actual chassis, it is easier for you to look at it.

If I were to think the two inner pins are at the bottom (well the chassis is upside down so right now they are at the top), but I mean one fat and one slim pin, they have to be pushpull xfmr ends.
The two outer pins (two fat ones, again I am making a supposition) have to be the field coil. One of them also receives the centertap. (If you look at the plug, the top left fat one connects to both field and center tap).

It seems to me that if my presumtions were correct, your chassis is miswired same way your speaker is.
People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
