[GreenKeys] Kleinschmidt TT-4A UPDATE

[Steve Garrison]

As to the set of alternate gears, most of the TT-98s came with 60 WPM and
100 WPM gears.  Whichever set was installed in the gear box, the other set
was in the "spare" position on the outside of the gear box.  The TT-4 I got
from Rice had the 100 WPM gears in the gear box and the 60 WPM gears in the
spares position.

Greg,
Nice looking TT4s. Looks like a set of alternate speed gears (75wpm?)
mounted near the motor.  I would think that you should be able to connect
both units in series with a loop supply for testing sending and receiving
one to the other.

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. 

They are both actually model TT-4C not the earlier TT-4A as I thought.

I have uploaded a number of pictures starting here

If you want some additional pics taken of particular sections of the units
please let me know.

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.

I have a few questions:  (I am sorry I would do a search on greenkeys but
that function does not appear to work).

1.  On one unit there is some mild surface corrosion (white oxide) - what is
the best and safest way to remove it?
2.  Can someone advise me as to where I might find a operational/service
manual for this model as a pdf/doc?
3.  I am interested in hooking them up to print from the internet, is the
RTTY site a good place to start?
4.  What sort of grease is ideal?
5. Any do's and don'ts?

As you can tell I am a newbie but I have an interest in mechanical things
and believe I am reasonably handy.  Most of all, I just love the look and
sound of these machines in operation.

Thanks for your time,

Greg
