One channel of my relatively new "old" Ballsie seems to have gone south. I am getting about -14vdc on the output. The other output is fine and the inputs of the board show no voltage from my dual mono Opus boards which previously had been working very well. It seems odd to me that just one side could die since both channels share opamps. I believe that the input of the LM49720 shows no DC on it's input. I have checked and double checked the wiring and also reversed the inputs to the Ballsie board but the problem stays on the same side.

I went ahead and ordered a Ballsie Lite so I could get back to music but it does seem odd that a board would fail so soon and just on one side.

Any ideas?

Best,

Paul

PS. Do you have a place where we can find the schematics, manuals, and board layouts for products like the Ballsie which get displaced?
