This is how its should work.

As there are 2 raws with resitors on every deck.
So if you remove 4 decks,it can be run i balance mode.
 
Soldering a stepped ladder attenuator for a balanced amp is more difficult than soldering the amp itself, or at least as difficult. 😀

How many steps does it have? What's its brand? Is it an Elma?

Can you list the values of the resistors also?
