Leslie speaker-out modified to guitar cable out?

[SoftMatching338874]

I gotta a T-212, spinet organ.
It has a leslie speaker inside, but I wanna use with external speaker.
It seems if you plug inside wires of guitar cable into two holes of 7pin? leslie output, you can use ordinary guitar amplifiers.
Is that possible?
Or Do anybody know how to modulate Leslie speaker out to unbalanced guitar cable out?

Cheers,
Fred.
