Re: Ferguson 247T: huge console TV set.
I'm certain now that the scan coils are not faulty. I've hooked a another scan assembly, albeit not Ferguson, and when those coils are connected into the line circuit it's the same effect, the EHT dies.
In these line timebase circuits the stored energy in the scan coils is at the time of flyback contributes the first part of the scan. It could be possible that another component is breaking on account of the extra energy from scan cols.
