Oscilloscope woes

[Tony Moore]

Hi all,

This is probably not the right section for this post but it's the closest I could find.

I've just bought an old scope from someone on Ebay
and it seems to have a fault. I didn't pay much for it so I'm not too gutted but I wonder if anyone could look at this trace of the test square wave and comment on if this is likely to be a simple problem to fix or if it's going to be too hard to locate.



I have found someone who might sell the service manual so it could be a little side project to fix it.


Thanks,
Tony
