[QuadList] Another Switcher Picture Puzzle

There was a lot that was done by other folks for RCA.  The monitors  were 
made by Conrac and others.  The TO-4 scopes were made by someone  else.  In 
the areas of cameras, pedestals were made by others.  The  Film projectors 
were usually RCA but they did use Gray, Kodak, and other  projector makers.  
The cheaper educational stuff was made by others a  lot.  The encoders, 
racks, and patch panels, internal power  supplies, etc.  
 
So it was like any other manufacture, a lot was made for them.  They  did 
the integration for you.  Or the parts were used in a bigger  item.

Chris covered everything!  Excellent  answer.
 
I actually thought 2 things were unusual.  The  non-composite that he 
mentioned, and the fact that RCA used a Ball Brothers  SEG in the switcher.  How 
often did they incorporate something from  another manufacturer in their 
products?
 
Here's the first page of the catalog.

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
