16h12 Problem with sudden change of params.
Recepies did nopt store corrected orbit: due to erro in EL steerer.
In continuation to yesterday study Jean Noel soldered in parallel 33 ohm : effect on orbit visible . Need to find correct shunt resistance (temperature) and power > 10 W.
Power supply does not show any sign of problem.
