Output Transformer from Field Coil Speaker Tube amp

[pleasantbullet]

I bought this old Wurlitzer Organ tube amp for 35$.
push pull 6L6's, with 5u4gb rectifier.

the amp is immaculate.

I dont know much about field coil speakers, so i was wondering what the secondary wires are for on the output transformer, as i think they are slightly different than guitar amp output transformers.

Primary wires: blue-red-Brown
Secondary: Green-Red/yellow-Red/black-yellow

Yellow is tied to the chassis. so i assume thats the common.
and the green is at the opposite end, so i'm assuming thats the 8ohm winding, as the speaker that this amp was used with was a 8 ohm jensen.

So what should i do with the middle two? cut them short? or tie them together and tape off?

any thoughts much appreciated!

If it's the 8 ohm speaker tap it sould resistance check at above .4 ohms and less the 1 ohm.
When doing these low resistance test you can not hold the metal portion of both test leads as the meter will read thru you, so only use one hand to grip the test lead and the wire end!
Cut the un-needed leads off with enough lenght to to fold over and heat shrink the ends or crimp on a bell connector .
