[QuadList] Another Switcher Picture Puzzle

[Chill315 at aol.com]

What gave it away is the style of the mix handle.  RCA all the  way.
 
It is a RCA PTS-1 Switcher model 8/6D
 
RCA sold this in the educational market.  They called it Professional  
equipment.  
 
It is a Ball effects panel at the top right.
 
What is unusual is that the switcher is a non-composite switcher.  The  top 
A B buss were the mix effects that fed the wipe and key generator.  The  
upper right panel did the control of that buss.
 
The output was fed to the MIX only buss in the center.  The delay was  
matched so that you could dissolve in a key or wipe.
 
Lastly, the busses fed the COMPOSITE switches at the lower right.   Here 
would be the early quad machine or helical that was not locked to  house or 
the network feed.  
 
RCA built this from little modules that were jumped together with little  
cables that had phono connectors at each end.  These would fit on a 1 RU  
tray with three modules per tray.

David's pic of the TE-60 reminded me of a system that I  thought was 
interesting because of an uncharacteristic design feature for the  manufacturer, 
and maybe a bit more difficult to identify.  It was  definitely quad era, and 
I've seen one feeding a VR-1100.
 
1) Who made this switcher
2) What was the model number
3) What's unusual about it
