[GreenKeys] Kleinschmidt TT-4A UPDATE

[Greg Arnoldussen]

Thank-you Jim for the manual much appreciated.  The tuning fork is still in the case, it will be an interesting exercise using it once the two machines powered up.

regards,

Greg.

Greg - Attached is an operations manual for the TT-4 series machines. I may have a maintenance manual, I'm not certain.  I am in the process of moving and all of my stuff in boxed up at the present time.  I found the attached on line.  There my be a maintenance manual in .pdf format out there.  I'm not familiar with this particular model, but did work on Kleinschmidts in the Air Force.  I do have a .pdf of the AN/FGC-25 which has a printer very similar to the TT-4.  I can send that if the correct manual is not located.  
 
It appears that you will need a tuning fork to adjust the motor speed once you are able to power them up.  If these are like the units I had worked on, they use selenium rectifiers to obtain DC.  These give off a very bad odor when blown.  
 
This is a start.  Have fun.

>Hi all.  After some negotiation I ended up purchasing both units today for half price, I had a good look at them and  they appear to be in good working condition, but they are 115 V machines so I am going to have a painful week long wait until my engineering friend travels up to give me a 240 to 115 V transformer to get them whirring.

>One was made in 1968 and the other 1969.  They are identical and both ex-Army.  As I said, although I can't actually power them up yet they both appear to be in quite good condition and do not appear to have seen a lot of service.  One of them even has a full roll of paper still on it and some type on the paper as well, so there is a good bet at least one works.  Both came with a mechanical cover but only one with a cover that encases the unit completely for transport (that Steve mentioned).  The spring loaded clips are deadly - there is no way that cover would come off in a hurry.  The previous owner believes he may have the cover for the other unit as well, so I'll find out later in the week.
