Have not opened the bag as the IN-12A tubes just showed up today, the board about a week ago. Looks well built, but will likely find myself altering it to fit my needs; I.E. the back-light LEDs mounted to the PCB will do nothing if using remote leads from the main board for the tubes. Also, I will likely move the push buttons and USB connector to somewhere else as it really limits the mounting options.
It did not arrive! And there is no way to complain!
