has anybody tried different diodes?
not related to this problem i mean, just in general?
in europe HV diodes are hard to get and expensive, as i just discovered when my scope started showing symptoms.
given the fact that you cant walk down the street here without tripping over vga monitors sitting out by the side of the road, has anybody tried extracting the diodes from a 32Khz lopt?
