The second anode voltage was too low and causing the HV rectifier arc internally. Had close to no HV on the other set also, so I just changed it any way. I replaced the doorknobs with 15kv ceramic disk caps, .001mfd. I had to modify the mount and connections to use the cap on the underside of the chassis. Special attention to lead placement and spacing is required when modifying. You don't want intermittent arcing. Only make this change if your sure about the doorknob. Don't forget that troubles with vertical output transformer can load down the B+ boost voltage too.
