Hi Finn, Fabs and all, (sounds nice, doesn't it?) As you probably know by now, I didn't read the original posting that well. I thought the new wounded MOT was ment for adjustable supply not for shunt. Sorry about that. I think my laptop screen is too small for all that info at the same time ;-). I think I'm gone try this also. Looks great! Ruud de Graaf Greetings from Holland
