My First Service! Pioneer SX-650

Back in March of 2024 someone purchased a receiver that I had restored. Shortly after they received it, they messaged me to let me know how much they were enjoying listening to vinyl with their grandson and that brought me a lot of joy. They then asked if I could work on their Pioneer SX 650 stereo receiver that was having issues with the phono section and all of the lamps were out. I want to start offering more services but my time is limited so I said it might take me a couple of months but I'd love to work on it! I deep cleaned it, replaced some faulty components, fixed any issues I came across, replaced the lamps, and lubricated the controls. It now runs perfectly and this videos shows how I got it there.

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.
