Picked up a pair of SDA-2B's, great condition, and sounded GREAT!
Now that I have them home and am ready to connect, I am concerned that my power amp is not common ground.
It is my understanding that the SDA's require a common ground. My power amp is a Sansui B2102, late 80's.
I used the multi tester checking the continuity across both left and right speaker ground posts, there is slight movement on the multitesters meter, but not full.
Does anyone now if the Sansui B2102 is a common ground amp?
