Hello,

I recently got an A-188-1 256 stage unit and have come across an issue with the direct bbd out and feedback path.  First off I get no output at all from the bbd out which means no feedback at all.  I tried injecting another signal into the feedbak input but even this does not produce any difference.  I am fairly handy with a soldering iron so I was wondering if anyne could shed some light on what could be going on.  Everything else on the unit works fine including the mixed output including the polarity switch for the mixed out.
Ideas

thanks,
b.
