Just got this power supply in from France. Can anyone comment on the internal electronics and any potential modifications?

yuri i can look to mine , and send you to pm . at first of course relay socket and
relay trls 42? ( looks like the trls43 of 100 ws ) are missing , the tool is useful to take out the betrieb lamp .
apart the missing valves ( ds311 are rare ) the others are normal
valves . some yellow wires seems to be cutt
the NTG2 was produce during the war , by LMT in France , (you see sometimes LMT in meters ), for the germans
LMT = Le Materiel Telephonique
i have seen some used by french army , the french put 6v valves , and in
place of DS310 they put valves like 955, it was my warning , in an other mail
as heaters are in this case 6v , they had made the transformer wind for 6 v
DS 310 who are rare , will be dead . externaly it looks good
may be funksammler will post a picture on forum ?

I am uploading some pictures of my power supply, which shows the relay and the missing capacitor block on the back of the front panel:

Immaculate SEG-2T configuration Funksammler!!
I've included a closeup of the missing capacitor area. Looks like the wires have been professionally "cauterized" during manufacture, or sometime later, since the tubes put on the wires are of a period material.
A bit strange.Comment

funksammler , about special connector , i believe it's a marine connector , mine is not the same , it's shorter , and wear an identification plate , i have send pic to yuri ., who will may be post it as comparaison ?
i have open one of my power supply , and it's like that of yuri , some cables are wrapped and insulated , so it's not cut .
note also this : there exist a special mast , weight is 55 kg and 11,3 meter high
it's not a usual mast , there are inside a coaxial line called the " lechersystem " mast type : STM2 LN 20.028

connector
hello i have carefully look inside my 2 power supply NTG2 , and i clearly see that this 3 contacts male connector , is with a thread , it means the connector
must be screw , for holding it firmly , i am shure the FS conncetor is for marine power supply , like that for the hagenuk ha5k39 .
my goal is not to make troubles on this forum , just correct something
that is wrong, if there are no answers it don't help, there are certainlely more then 3 people on this forum who has a NTG2., and can give advise .
a difference i see , is the following , german one seems to have a carrying
handle like on german sets , but those , made by LMT have a carrying handle like on french pre -war sets ( ER40...) i also believe that french did'nt put C53
interference capacitor .
