You say you bought a 125 series audio output transformer, exactly which one did you get?

Regardless, drill out the two rivets that hold the original audio output transformer in place, and mount the new one where the old one was.

Correct, the new one has three wires for the primary and six small terminals which are for the secondary. These terminals have numbers under each, correct? (1 through 6) Assuming you do not have the hookup diagrams which should have come with the transformers, I'm going to save you a bit of trouble on the audio output.

Before you remove the old audio output transformer, look carefully at it. If you look closely, you will see one bare wire going to a particular terminal on a terminal strip close to the transformer. This is important - it is one of the output leads. The other lead is grounded (soldered) to the frame of the transformer. Now with the new one, we are not going to solder any wires to the transformer frame. Instead, look carefully at that terminal strip closest to the audio output transformer. Look for a lug riveted to the chassis on that strip that also has a terminal sticking up. This will be your new grounding point.

You will have two choices to try for your speaker output. First, try connecting the speaker output to terminals 2 and 4. Terminal 4 should be connected to ground.

If this does not sound to your liking, remove the ground from terminal 4, remove the connections from terminals 2 and 4 and use terminals 3 and 5, with terminal 5 grounded.
