Unfortunately cooking the overwind has not made any difference, so I'm now trying to remove the overwind from the LOPT as suggested. I will then run the set measuring the boost voltage and see whether it still drops, or remains stable.
Unfortunately, having taken the lopt out, I can't see how to split the rectangular core. It doesn't look laminated, neither is it bolted together like modern ferrite cores. Any ideas please?
