Hi all,
Following previous observations regarding the rate of oil leaking from
the 1B01-0 tank end, I looked today at the level of mineral oil present
in the tank end. Using a cable tie, I measured 16 +-1 cm. Just for
comparison, I opened 1B01-1 also where I measured 18 +-1 cm.
1B01-0 leaks at a rate of ~180ml/week and at his rate, assuming that
the tank end contained originally 70l, it will empty completely in
about 390 weeks.
I noticed that there was mineral oil quantity under the lip of 1B01-10
We need to install a plastic cup under it the earliest possible.
In addressing tank ends that have lost significant mineral oil over the
course of years, we need a small container (1-5lt) so that to fill them
up manually (no need for the pump) systematically (I'll buy this container
ASAP).

PS: 1B01, both sides have their high voltage *cable* reconnected but I did
not power up the tubes.
