actually there does seem to be kind of an intermittent problem, but it seems i can fix it by turning off the phantom and then turning it back on… anyone else experience this?
hmmm… I dunno, what I did, but it seems to working now… is it possible the tubes just needed time to warm up? and my 15 or so minutes of trouble shooting was just enough? I guess I should know that tubes need that time, but I feel like it should probably say something in the “instructions” about that!
