tech8, I have a question for you. I replaced ALL of the caps with 33uF 35V, before I did all of the work I was getting a clean power on self test but failing SPC. Now I get s failure on the aquisition on the power up self test and of course, it still fails SPC. What would you suggest checking? Is it critical that the 10uF 35V caps have a 10uF value as oppoed to what I replaced them with (33uF)? The aquisition board didn't have any leakage or corrosion at all before I changed out the caps. It had a sticker on it from 1996 with a technician's initials. I'm wondering if the caps were replaced in '96. I checked all of my work and everything appears to be good so I'm a little perplexed that it now shows a fail aquisition on start up. BTW, I also replaced the 10uF on the processer board with 33uF and that tests clean. As an aside, the worst caps I replaced were those on the control board in the front. They were leaking and starting to corrode.
