OK.. making progress after some good suggestions after my last post. NOW I need to tackle the replacement of the AC cord. No room to install a new plug in the unit so have to hard wire in a new AC cord. Was going to remove the existing plug and wire it there. Problem is the transformer. I need to remove it so I have room to work. BUT can't reach the nuts on the chassis so I can remove it. Any suggestions??? Or do I just struggle with the transformer?
