help with Hickok 539a

[mrmalace]

I found this tube tester in mercaplace, it has some problems, one of them is damaged rheostat-potentiometer 200 ohm 25 w, which I already ordered, it also has 9 loose cables that go to the sockets attached photo, I have tried to read the diagrams but I have not been able to find the position of the cables, I know that most of them go to the noval socket, I am new to electronics hoobie and I am learning.
some information or photo of the 9 pin socket would be of great help.

Post your tester's front - looks like one switch is missing? Reading the diagram of 539 could be really painful

Hi, thanks for your response.
Yes, a rheostat-potentiometer 200 ohm 25 w is missing, which I am going to replace with a new one, I have had a hard time trying to understand the diagram.
