the probe skated
i had to use the stupid, huge. 0.22uF Mundorf caps and it covered the 9 pin socket points.
pin one is under the cap, close to Q3 and the heat sink. I had to guide the probe straight down. i couldn't see it but im pretty sure i shorted Q3 and it incinerated everything around it.
for good measure i replaced Q1-4, U1&2 and 8 surrounding resistors.
i just this minute finished putting humpty back together again. i will light the mains in a few minutes.
