[QuadList] TRT-1 Pictures and How to tell if Color

[Chill315 at aol.com]

The picture on the cover of Broadcast News does show the capstan roller  
reversed.  It also has an early version of the control panel.  The  Control 
panel has two hour counters on it.  There are several knobs missing  that were 
on the production version.  The tape path does not show the tape  counter.  
The heads were moved around on the pre-production version vs. the  later 
production units.
 
The control panel wiring was changed after the first 40 production units  
were made.  I only have the schematics so I have not taken the time to do a  
through review for the differences.
 
The pre-production units in the photos have a lot of items in the tape path 
 that was not in the production version.  I cannot tell where the audio  
heads are located.  If they are close to the capstan then the displacement  
would be non-standard.  Also the pre-production units do not appear to have  a 
timer in the tape path.
 
How do you tell if there is a color rack without the seeing of the  rack?  
If the machine had the solid state proc amp, then look to see if the  color 
module was installed.  Third module from the left.  This had the  color 
burst and phase controls located on it.  The top two knobs are the  record phase 
 The left was the course switch.  The right was the  fine.  These were set 
in E-E mode.  The center know was the playback  phase.  The bottom two were 
the burst and chroma levels.  It was also  two slots wide.  This was a part 
of the color kit.  
 
Now how did we keep SCH on this machine?  Just kidding.
