[GreenKeys] TGC-14(V)

[Andreas Müller]

Hi everybody,
yesterday I got an obviously complete AN/TGC-14(V). The TTY itself is called 
TT-297/UG. Can anyone put out the difference between the TT-297/UG and my old 
TT-264/AG except that the former is green and runs on 26VDC and the latter is 
crincle black and runs on 115V400Hz? Also the rear connectors are different, 
but the one of the TT-297 could be homemade. Does anybody have a connector or 
the matching junction box to hook it up?
Some people told me that the 115V400Hz TTY should run on 50/60Hz also. Can 
anybody verify this?
Thanks for your help
Andreas, DD1LM
