Thanks (just about to go to bed, but did another quick check). IC9 pin2 is definately showing the same as pin 1. (problem)
The oscilloscope works in reverse:
.5 = 10v/ 2cm,
1 = 10v/1cm,
2 = 10v/2.5cm.
So in these photo's 2cm =10v approx
It's an old Australian made oscilloscope called a bwd 539d. I'll have another go with it tomorrow night (will turn off auto!) I've mainly just used it for audio in the past.
Thanks again, I will also change over ic9 tomorrow night. (thanks for the tips)
