Haynes Organ King Amp and Speaker

[roemer]

Just joined this forum~ Great Picture of the Panther Organ with the Haynes Amp. I have that same amp but with the double keyboard Panther Organ. This was the organ my dad purchased for me when I was 11 years old in 1965. Wanting some info on how to hook the power cable to the amp section. Been a while and just want to make sure, It has a male and female power connection on the back. I would assume the male connector is the main power feed and the female is aux power maybe.

Any help would be appreciated.
