Hi!
Been Reading through all lv103/105 threads whitout any specific preamp issues, could use some pointers here, this is maybe a tad to complex for my knowledge to be honest. at D2 and D3 i have around 90-80V and 40-35v (seems to vary a bit from cycle to cycle) checked every thing except resistors and caps, (desoldered Components and tested these) Everything seems ok to me, not really to bad thermal damage to this board as they usually would be. if you want the schematic please pm me.
