I've recently decided to get back into guitar now that school is out for the summer (we'll see if I actually keep my promise, I say I'm gonna do a lot of things every summer). Anyway, so a few months back, I turned on my amp and I got an extremely loud bucking sounds out of it as shown in this video: https://vid.me/ubh

I know it's a pretty lousy amp, but I want to try repairing it for educational purposes more than anything else. I'm a senior computer engineering major and my analog electronics could use a bit of a refresher.

If it helps anyone out, Gibson provided a schematic for the Studio 10. I presume the 10S is the same amp, just in a slimmer form factor. http://www.gibson.com/Files/schematics/Studio%2010.jpg

I presume bad capacitors are to blame; the amp has been sitting for about 5 or 6 years (college really takes a toll on your hobbies lol). Last time I opened it up, some of the caps near the power supply looked slightly bulged. Apparently I've heard that they can sometimes go bad after remaining unused for extended periods of time.
