Hi Guys
Back again first project Harman/Kardon 560 Blew fuses as soon as pluged it in. After poking and proding around seems like the secondary has an internal short. Disconect the secondary leads from the power board short in board seems to go away but remains in the leads from the transformer to ground. There are only three leads two ends and a center tap. Al three read short to ground. They do have contunity to each other but there is no resistance from the ends or from the center tap to the ends. I would expect to see some reisitance in the secondary windings.
Hope it is not a door stop it has a interesting face.
Thanks Al
