Man, I wish I could find a pic of my first rig that I built in high school and used in college until I got my Ampeg.
Yamaha B100-II head I bought from Daddy's Junky Music. Tolex and cloth were a bit worn, but sounded tight.
The cabs...oh the cabs. A pair of cheap 3-way speaker boxes donated by my uncle, just particle board and vinyl woodgrain. Proceeded to fry the stock speakers, so I yanked out everything, loaded in Radio Shack 15" drivers, covered the holes for the tweeter and horn with cardboard, sealed with duct tape, and reinforced all the edges with a couple layers of duct tape. I have no idea what the wattage or impedance of those speakers was, but they were cheap.
It looked totally ghetto but sounded ok and was amazingly loud. I remember one project, my buddy had a JCM900 and a 1960A (or similar) cab, and he liked to crank it up. Drummer couldn't hardly hear the guitar, and my volume was at like 6 or 7.
