If it is the dual mono model it does replace the balance...but when stan warren designed it the were mirror image channels so neither channel relied on the other.I really enjoyed mine back then.replaced with higher end vol atteuators bumped it up another level.paired with a bk st-140.Those were simpler days.still think alot of that little preamp...
Dual volume controls on superphon pre-amp
Buying a superphon pre from my dad and he informed me that it has dual volume controls. Of course I can see that one could control each speaker with corresponding volume controls but what is the purpose of this. Dad does not know and he knows of only one other pre with this system.
