I'm going to assume the equipment was not recently working before it came to you. In which case...

You should first clean, test & get the Rectifier supply working right. It may need a restoration (parts replacements, cable replacements). 

Then go to work on the TG-7. Clean out the crud. Perform the manual's lubrication points. Check the magnet coil for continuity. Then try setting it up with the Rectifier supply for loop current & try running the TG-7 to see if keyboard inputs are correctly printed. Only then should you worry about any other stuff like getting it on the air for RTTY.

Above all, read the manual's longwinded descriptions of how all the components work to produce printing. Identify all the parts mentioned by looking at the machine, too.

It's been two weeks since my post asking for help.  I did get a good

response, but not actual answers to my questions, so I'm going to try again:

I have a TG-7-B TTY.

I have a TG-26-A Reperforator (without the cover).

I have a TG-26-B Reperforator (apparently complete).

I have a Rectifier RA-87.

I have a Flesher TU-170 RTTY Terminal Unit.

I have the manuals for the above, except the TG-26-B.

I THINK I have the cables for the above.  All but the TU are in chests,

and apparently came from Army MARS.  I got the TU from Fleabay.

What I need is some advice and guidance for getting this stuff up and

working.  I want to use it with a Yaesu FTDX5000, so will build the

appropriate cable.

1) To just get the RTTY up, do I need anything other than the TTY, TU

and cables to/from TTY, TU and radio?

2) I believe that the TTY is 115VAC, and the selector switch just sets

cycles.  So I can plug in and go? Does anyone know the amps this uses?

I'm not finding that in the manual.

3) I'm seeing conflicting (or at least conFUSing) info regarding power

for the Reperforators.  The manual says that "governed series motors"

run on either 105-125VAC or 105-125VDC.  Then it says that the "jack

box" needs 105-115VDC.  I THINK that means that I need to plug the

Rectifier into 105-125VAC, then the Reperforator to the Rectifier.  Or

do I even need the jack box?  I see that it connects to line units,

which I don't have and apparently don't need.

4) The manual I have only covers the TG-26-A.  Is there anything

different about the TG-26-B that I need to know about?

Thanks,

Keith KA7EKW
