Glad to hear of another DualTone owner! I have an original soundbox with the DualTone name and patent number on it (1392677). Look up the patent and it shouild show the sound box shape: a pentagon with clipped corners. I have photos and will post them when I can. Life is insanely busy at the moment. The motor is 'The Motor of Quality' which was used in many off brand machines. Ortho Fan, thanks for posting the patent on the tone arm. I've had no luck in finding any info on the company that made this machine.

I bid on this machine for it's gimmicky tone arm and and far as I'm concerned thats all it is: a gimmick. But the machine sounds surprisingly good! I attribute that to a mica diaphragm in excess of 2 inches in diameter; not the split arm. I really enjoy listening to this machine. The data plate is conventionally located at the rear of the motor board, not on the exterior

Very happy to share info and photos with you about this machine. Hopefully I can find some time this weekend to upload some photos.

It have one base screwed on the motor board, then split into two barrel tone arm, the the two baerrels join back into one, and loop to the left to hold one reproducer. All the hardware could be brass and was gold plated. Unfortunately it have the wrong reproducer. I wonder what the reproducer look like. Any information is appreciated.

Here are pictures of the Dual Tone Phonograph.

I hope I will get some comments and help with the reproducer now that I post the pictures.

Thanks,

James
