I've had this AVR Pioneer SC-07 since new back in 2008. Trying to fix some transformer hum that's starting to become audible over the last couple years. I have a bunch of IT hardware assembly experience, so I was thinking of trying to follow this video and re-gluing the transformer fins together. Will that work with the transformer that I have here? And secondly, if I unplug the power and then this transformer, there is no residual power in the transformer, only in capacitors?
