I just acquired a K200B-2 amp head only, I believe a 1971. I'm in process of either building a cabinet or purchasing used. It appears the K200B-2 amp would need a cabinet with 2 separate speakers, each with it's own jack. What wattage and impedance should the speakers be? I have a line on a Music Man 212RH-150 cabinet with EV speakers, but it is not wired. It was someone's project that didn't get completed. I haven't looked at it yet so I don't know the wattage or impedance of the speakers. It's suitable priced and a serious consideration in place of building a cabinet from scratch. Also, what function does the footswitch serve for this amp? It did not come with one, but I do have a single button one I'm considering using. Thanks in advance. Rusty Fingers
