@Mallard4468 posted:Thanks for posting this information. I have the dual version, and the power ceased to work on one side. (Bought new about 15 years ago, has circuit breaker button, has seen moderate use.) Awhile ago, I opened it up but couldn't see anything. Hearing about the traces is helpful - I'll give it a look.
Take the small board under the pushbuttons off and check the copper clad tabs. This is the usual point of failure on these transformers. Both of mine had this issue. There is a big plastic block with springs in there. Be careful when removing it or you may be hunting springs. The contacts could be broken or have a failed solder joint. I got lucky on one and just had to position the contact and reflow. The other one was a contact swap. If you have to get contacts, I highly recommend getting extras.
