[QUOTE="Family_Dog, post: 1086875, member: 82"] I did use a scope as well as a DMM, but although the scope should have made trouble-searching a tad easier, it would only have been obvious during the actual fault condition. Using a DMM on the diode showed that the diode tested fine, but it was faulty and it leaked just enough ripple to trigger off the protection circuitry. The various on/off repairs are detailed in my vintage equipment thread, but victory followed this post: https://www.avforums.co.za/index.php/topic,38005.210.html -F_D [/QUOTE]
