[GreenKeys] Model 19 parts and questions

[Kevin H. Phillips]

Hi, folks
I need a couple of parts for a Model 19 I recently bought as well as 
some advice.

First for the parts, I need the cord that pulls the carriage back on the 
return.  The second part I need is, I think, one of the Y-levers.  It is 
the longest one.  I hate to admit it but in my ham-fisted attempts to 
get the thing running I got the carriage off track and ended up with the 
couple of broken parts (that I know of). 

The set has been sitting unused for 35-40 years in a house which had 
been closed up but still had utilities connected and running.  The man 
who sold it really thought it would still be in operating condition.  
The AC has been kept on in the house but this was in south Louisiana so 
the humidity level, even with AC, is much higher than anyplace else!  
The set has a Signal Corps RA-87 Rectifier.  I had to replace the DC 
cord.  The machine runs but is running open.  The bars under the 
carriage just vibrate back and forth.  (I'm new to teletype so I'm not 
familiar, yet, with a lot of the terms.)  The tape punch works fine but 
the keys on the carriage do not operate whenever a key is pressed on the 
keyboard. 

One question I have is whether or not the 60ma loop is being supplied by 
the RA-87?  Second question is, assuming the loop is supplied by the 
RA-87, what/where should I check to get the thing to run closed?

One DC socket on the power supply has apparently gone dead.  The other 
is still active but the plug doesn't fit well at all.  I'm tracking down 
some schematics and may try to have the PS rebuilt.

My direct e-mail address is kh-phillips at 9-5usa.org.  My cellphone number 
is 979-229-8954 if you think you could talk me through some 
troubleshooting tips . . . or just want to chew me out for screwing up 
the machine!  ;-)

Thanks,
Kevin
