Hi gang.

In reference to this thread:
https://www.vintage-radio.net/forum/...=159953&page=2

a wire has broken off the input to one of the delay lines on my OS3000. My main question is this:
The delay line does what it says, and introduces a delay to the timebase so the first part of the trace is visible. In my case about 95 micro seconds.
Presumably this can be achieved by making the delay line a precise length. therefore would it cause a problem if I cut , say 2-3mm of the core to find the end of the broken wire?
Would that amount of reduction in length be significant? Would I have to do the same to the other delay line?
I have zero experience of delay lines etc, as I don't think they generally give much trouble, so please help. I've spent enough time on the wretched thing, I cant give up now!

Many thanks
Tim
