Re: Memories and other stories from Pye etc PMR engineers.
That's interesting David, I have never thought to see if they can be improved at all by a thermal cycle. I'm not sure I still have any to try out the idea.
Not having that book - what temperature would be required to have an effect?
I do remember that F29 grade was really sensitive to it and it was often best to replace those cores "on sus" before starting any serious fault finding.
