As I was checking voltages for the first time, I believe that I shorted A8 and A9 with my ohmmeter probe.
I thought I heard an audible "click", and whereas before both LED's would glow red, the one I shorted no longer glows.
I initially measured the correct voltage at A8 which is 1.5v, but now it is measuring 13.8v.
I'm also getting some wacky voltage readings elsewhere now, where initially the reading was fine. My thought is this is related to
my mistake described above.
Do I need to contact Bottlehead and order a replacement LED?
Also, could I have done any damage to the tube that is in that socket?
Thank you everyone for all the help here along the way!
