Help rewiring Zenith 11S474 output
 

I need some help putting my 11S474 back to original condition. The first picture shows it modified to work with a PM speaker. It used pins 1 and 5 marked in the second picture.

I picked up a Zenith 49AG424 field coil speaker to use. It has the correct 670 ohm field, pins 2 and 3 on the speaker output jack.

That yellow rubber wire comes from the 6X5 rectifiers. I just need to know how to wire this back up. Thanks for any help!
