JBL Olympus C-50 loudspeakers

My Dad got these while on Wake Island in 1961 or 62. He has a Marantz Model 7 amplifier and a letter from Marantz dated April 26 1962 that told him he was too isolated from the rest of the world and they would send complete details as well as the materials necessary for conversion to Model 9. The C-50 has one woofer. I don't know how to hook up the Marantz either. I have them playing through a receiver right now set to radio. I have an extra turntable I can hook up to see how well they sound.

The Marantz is a Model 7 and I don't know if my Dad did the conversion to model 9 or not. The speakers are playing radio with a old Pioneer SX 450

There is a plug built in to the Solid State Energy Transducer. Dad wanted to exchange the marantz model 7 for the model 9. Being on Wake Island made that cost prohibitive for Marantz. They supplied every thing needed for the conversion, but I don't know if he did. I'm trying to find out if everything is functioning properly so I can try to sell all of this. I don't have room for them and I don't want to put them in storage.

that photo is the solid state transducer. I have all the manuals and catalogs from the time period. It's the S8 speaker configuration.

Thank you all. I am confused is why I am confusing you all. The transducer hook up needs clarification and since there is only one component I assume he did the model 9 conversion, but how do I know? I would like to add photos but don't know how.

OK all I put photos in the create system with the tag needs a new home
