Tre,
yes, I was expecting the same result... but with both grounds off the RCA's, the amp is the same.. the real bad hum which you mentioned, will only occur if I disconnect the other end of the coax... and I have to disconnect it on both coax cables for it to do the big hum.. I know that sounds outrageous, but I kid you not, this is what is happening. I tried grounding the other end of the coax to other points on both sides, but no difference..
It sounds insane, I know, but that end of the coax is suspicious that it behaves like this. The path to the 12by is pretty simple and I can't see any other place it can ground.. I do think there is something up with the other end and not the end of the RCA's
It was suggested that I check DC voltage from all the grounds to chassis and the RCA grounds and the filter supply grounds all drop to "0" DC volts.. when I checked last night.
again I seriously thank you for your replies on my thread, I am losing all hope on this lately..
J
