How I don't learn from experience

On the morning of last day of the year I fixed a friend's audio amplifier, a Luxman L30. The right channel had gone. We'd bought the replacement transistors on E-Bay. They arrived on the 30th. I'd previously looked inside the amplifier and thought "buggar me this is going to be awkward. I'm going to have to desolder four heavy duty power duty transistors just to get at the circuit board."

You'll be asked if you want to execute Menu.Exe, click on that opt...
