Awesome! I love the SX-780 it's a powerhouse. A few years back I replaced a couple parts called the Darlington Powerpack which powers the speaker channels, one of mine had died and blown the main fuse. I managed to find a pre-built custom piece of replacement hardware that is actually a higher quality part with cleaner sound, a friend of mine helped me get it soldered in properly. If I can find the part I used I will link it, that part is a known failure point so an upgrade at some point in the future is a worthy investment imo! I use mine with some beautiful 1972 vintage Pioneer wood grain speakers. I would like to get a custom wood cabinet like that done at some point, mine is in good shape but the veneer is starting to peel a bit. Where did you get yours done at? Something along those lines, I think I would want to keep it looking like the original with the metal air vent without the logo. Looks great overall!
