I have a feeling that the cotton insulation absorbed a lot of moisture and that is what caused it to flash over. I have completely rewound the transformer using teflon covered wire, I hope that is sufficient! -- 73 Warren K2ORS/WD2XGJ FN42hi http://www.w4dex.com/wd2xgj.htm -------------- Original message ---------------------- From: "Alan Melia" > Hi Mal thanks for that !!
