This is a machine that was built by Walter Welch. It is 2 Triumph top works and motors and they are geared to play together. Charley Hummel has this and Charley said that Welch used this to play 2 of the same cylinder at the same time, with the theory that no cylinder was perfect and that one would makeup for the deficiencies of other other. I am sure that there was some form of echo effect in stereo as I cant imagine getting the cylinders perfectly time aligned. Id imagine there could also be a negative phase cancelation as well due to slight delay of the same waveform.

I helped Charley load it into his van, it is very cool and quite heavy!

Dan,

Thank you for sharing such wonderful photos.

It is indeed very cool, and unique!

Such a contraption could also be used to make
tube dubs.

One cylinder plays, the other gets recorded.
The sound gets to the recorder via a rubber hose
coming from the reproducer on the other machine.

The machines run at exactly the same speed.

What's the scoop on the Electrola in the 4th pic, first post?

It is an electric motor Credenza with a tooled leather front. It is very nice.

Any idea what they are asking?

It was priced at $1750.

Thanks, Wes. Out of this Plebeian's league at the moment. Sure is a nice and unusual one, though!
