Heathkit AD-1307 Stereo Watt Meter

ALERT!!! I have gotten some constructive feedback in comments that I have made a mistake in the power cord wiring. I am working on a video addendum to address the issue. Thus, it goes without saying.... "Don't do what I do. I don't know everything. Electrical devices can be dangerous." I will link the addendum. [[ Read comments to see issue. Add your own comments about it as well. ]]

I am trying to slowly put together a circa 1978 Heathkit Stereo System of separate components. [ Tuner / PreAmp / Processor / Control Center / Power Amp.... etc. ] Well, recently found a deal on a Heathkit AD-1307 Stereo Watt Meter / Audio Control Center that will add to the collection. It wasn't in the best shape but that also means it was a good deal. Here is my work fixing and refurbishing the component. The process almost "screwed" me in the end.
