Electronics Repair Questions? Ask an Electronics Technician
Hello, My name is XXXXX XXXXX I will be glad to assist you.
When you see smoke rise from a unit and the wrong adaptor was plugged in, you can be pretty positive that the power supply transformer is now shot. This is the most expensive component in the whole Aiwa system.
Unfortunately, because the set is rather old by today's Electronics Standards, the power supply may be hard to find/ There are only two shops in the US that still repair and work on Aiwa systems (as Aiwa has gone out of business 2 years ago). It will require shipping the system to them, as they are likely not in your area.
Here are the links to contact the ones that will still work on this unit:
