Thanks,
Camera and flourescent lighting......color is prob close to yours....orange for sure.
Other than the knob control...how do you adjust the piezo preamp...inside?
thanks again!
Pull the back cover. On the little circuit board is a trimmer pot that sets the preamp output level for the piezo. A small flat-blade screwdriver (3/16" or so) is needed to make the adjustment.
That is the only adjustment in there to make, so it is pretty easy!
You may want to put a fresh 9v in there, too, while it is open. No telling how old that one is.
