!!I need help with an old UDSSR Tsch3-54 Frequency Meter!!

Hey There!

Recently, I found an old Tsch3-54 Frequency Meter, but sadly its broken. And thats where I need your help. Maybe you have a working one laying around? Or a similar one? Or maybe you have a circuit diagram? I dont know if it was built in Germany or Russia but its atleast 20 years old. Here are some pictures:

Its front.

The Thing in all its old beauty... Nixie Tubes!!!

And now we come to the part where you can see whats broken. Someone desoldered or snipped off the old power connector and didnt reconnect it. I tried to reconnect some wires but didnt turn it on because I didnt want to destroy something. So if you have one please send me a picture of how the power wires are connected because i cant really assume where you should connect them. Some more pictures:

Here is the Area where the mains power comes in. But someone messed it up and I have no reference how to reconnect it.

Hi,

Try this schematics for example - https://www.qrz.ru/schemes/download/16350
Use "Ч3-54" to find more about this meter on the internet.
