How in the world do you disassemble a tru-phonic reproducer?

(I have no idea, I'd love any help!)

Thanks.

I believe it has a lock ring, screwed into the back of the reproducer housing, much like a Victor Orthophonic. The 4 little nubs you'll see on the backside are where the special wrench is meant to engage with the ring. Apply some penetrating oil on the ring and let soak before beginning.

Thanks, Jerry!
