The doubler circuit in the attached schematic for some reason is not giving me 340v. Without load at most I get 330v. Under load it starts at 325v and slowly degrades to about 320v. I have checked the two 100k resistors one reads 103.5k the other reads 104k at 5%. Checked 3 caps(2 200v 1000uf and 1 450v 150uf) in doubler circuit area all are within listed uf range. I am getting a severe strobing effect from the lamp and I am suspecting this low voltage is the cause. Any ideas as to what could be causing the low voltage. And where I could start as far as trouble shooting.
