Valentine's gift (or is it a shameless trick?)

Phil,
When it arced, was an RF arc (ie., hissy and sizzly sounding)? Or was it a loud, sharp "SNAP!"? If the latter, it is most likely rectified HV arcing through a pinhole in the 1B3 filament loop insulation.
Re. the drive line, did it change at all with the contrast setting?
