[GreenKeys] Any DXD users??

[Bruce Gentry]

The video is great!, and what a collection as well:)   The style, sight, 
and sound of the DXD reminds me of  1930s and 40s automotive testers for 
ignition distributers with the whirling disc and flashing neon  light.  
I have seen these in books but never before saw what they do and look 
like in operation. The last distortion testers made were probably solid 
state and the size of an old multimeter. Still, there is nothing like 
the sound, styling, smell and overall cool factor of electro-mechanical 
digital communications gear. Thanks for restoring it and sharing the video.
