Denon RCD M38 repair

This Denon RCD-M38 repair was a long one but I've managed to trim the video down to one hour. Essentially, I needed a test amplifier for my workshop so bought this cheap of e-bay hoping for an easy fix. It was in a way but complicated by the multiple power supply parts on different boards and the fact you can't really measure volts properly on isolated boards. I got very confused at one point until I realised this, when I reconnected the boards the checks made sense and I located the fault to the audio output IC going short circuit, which in turn had blown the thermal fuse in the mains transformer. The main parts of the video show disassembly and reassembly as well as me chasing wrong voltages, but I got there in the end.
