I was using it with my polk SDA 1A.........I powered it on and the clipping light blinked and then I saw a spark. It still turns on, but the relay doesn't click on. I always heard people on the polk forum talk about "common ground" amplifiers with SDA's, but they never really said what that means. I took the cover off and I couldn't see any visible signs of damage. What happened?
Also the reason I had to get the fuse in the first place was because I turned the amp on without any speakers hooked up to it, which I guess is a no no.
I was using with my Carver reciever, which I have been using to power the SDA's. The receiver has a pre out and a "main in" with jumpers connected between them. I left the main in section empty and took the pre-out into the Tandberg. There wasn't even any sound, just a big spark.
