Thanks for the close-ups of the transformer. Photo #3 doesn't look good, with evidence of charring and so it's obviously been very hot at some point. It is quite possible that you might have some shorted turns. If so it will start to smoke again soon after you apply power. Try powering up without the rectifier fitted and do some voltage checks on the secondary windings. If the transformer is getting hot off-load you will soon smell it. Cheers, Jerry
