1976 Pioneer SX-550 Service - Part 1

Greetings everyone, this is a slightly late upload (been very busy) of this nice 45 year old receiver that came to me with some intermittent signal loss and noise. The issue was isolated (primarily) to the potentiometers and switches, but mostly a very dirty volume pot. Additionally, upon safe power up and during my preliminary inspection I located a 470uF 50v electrolytic filter cap that was getting extremely hot and was exhibiting a very elevated ESR. So, feel free to check out this brief part one video and stay tuned for part two, which I'll be uploading a.s.a.p.
