As noted earlier, I had some trouble with C7 blowing the chips. I am no closer to being sure what the problem was, but I am beginning to suspect a bad batch of chips, anyhow the original value is according to Phlips datasheet, way to high. I have now settled for a 2.2uF WIMA cap, and everything is playing nicely.
I had some help with my troubles at diyhifi.org, the thread is here:
