Re: Cracked LOPT Core
Dear John,
Thanks for your insight. The crack is wider at one side than the other, possibly pointing to mechanical stress. It is certainly wider than a hairline. I will be very interested to know what you make of the core saturation issue as I have two sets suffering from reducing width and EHT after thorough warm up. It is interesting that the cores were originally gapped.
I am naturally reluctant to have the transformers rewound until I am sure that insulation failure is the root of the problem.
Regards
Nigel
