Tuesday, November 13, 2018, 16:44: The anode drain current has increased 17mA since 11:23 am, however FC0 is still decreasing. I will keep monitoring to see if the behaviour of the anode drain current continues once FC0 has stabilized. If the anode drain current keeps increasing maybe we will observe the same failure from the previous FEBIAD.

Wednesday, November 14, 2018, 11:02 FC0 is stable but the anode drain current is still increasing and now is at 85 mA. It started at ~52mA. From the strip tool it seems to be a 2-hour period where the anode drain current is stable.

Tuesday, April 10, 2018, 09:10: Problem persists even at lower TBHG (330A). 

The output cable was removed and the power power supply seemed to behave better. This could mean that there is a short inside the unit, in the past the anode cable had melted into the cup.

Planning to ramp down the TBHT and see if the behaviour remains. If it does, I would ask to remove the unit for inspection.
