r10=330 ohm`s?
Yeah, Greg could confirm this... look under the board and see which leg of R10 has a trace that goes straight to REG_SW (LM7805), just like on the schematic. Leave that leg there... the other leg is the one you want to attach to C1/R1one leg of r10 connects to vr,and the other leg to r1,c1 junction?
connected r10 to r1/c1 junction,and at that point i get 39v,but at the other side of r10,there is only2v.i
sec=2*0-12v
can't help with much, except to say 80V Toroid would make lots of extra heat.
an 80V toroid would generate a lot of heat at the REG+/- (
