I made a power suplly that powers both a la7809 and one LM317. There is a circuit poceeding the carpacitor with two dual voltage comparators that are supplied from here. Four 22k timmers define a voltage condition. A sample taken from the LM317 output. All the trimmers are in parallel, samples even. The volatges programmed are like 4.7, 9.8,12.1, 14.5 or whatever is wished. So the timmers are programmed but on the second comparator the voltage is interlaced somehow the reacted theres a lump kind thing. a little jump.
