Hi, I'm new to the forum and to repairing amps and have just bought my first Kustom, a Kasino Club pa head marked model U100. I want to use it for keyboards, especially my Hammond M3 (which has a 1/4" line out). I have a speaker cabinet with a single 12" 8 ohm full range speaker for practice. I have some questions. As you face the back of the amp on the left are two 1/4 " jacks labeled "speaker output" and "One 8 ohm or two 16 ohm loads." How should I hook up the single 12" speaker? Do I just use one of the outputs ( and if so which) or both? Also, I am going to replace the filter caps and add a three prong grounded power chord. I don't know if I need to do anything else, but does anyone have a schematic for sale? I'd like to get one so I can work intelligently on this.
Any and all help and advice is greatly appreciated.
