Hi Ron. Wow, that was fast! Well, here's my problem- I didn't know that the chassis ground is positive, so I have the 10uF cap in backwards. Second problem- I put the 2uF cap in, it has a WV of 250VDC. I think this is pushing it, since on the side where the two 70K ohm resistors met is 253 VDC, and the other side is a -21,8VDC. I thought that i would subtract the two and the differential is approx. 240v. Thanks so much for your help!!!
