Let's fix some water damage! Technics SA 700 Restoration

In this video I restore a water damaged Technics by Panasonic SA 700 stereo receiver that was shipped to me all the way from Australia! It turns into quite a restoration with me replacing nearly 200 parts to get it back up and functioning like new. My transistor substitutions list: https://docs.google.com/spreadsheets/...

My name is Matt and I sure do love stereos! I got into this hobby when I was in high school over a decade ago. I had huuuge speakers in my bedroom and way too many pieces of gear (my mom was worried I would become a hoarder haha). I started repairing stereos for friends a few years back and decided to make videos about it! Now I repair gear for people. If you want to send yours in for repair, head to my repair form: https://forms.gle/Tk5xAEkGgVdyZ4w4A Some of my favorite brands are Yamaha (CRxx20 series receivers, CA 1010/2010 integrated amps), Harman Kardon (Twin power receivers 430, 630, 730, 930), and Sansui (X0X0 series receivers, AU 717, 919 integrated amps).
