@ Brf, Hi, If the op does not have problems with the krell amp its self, I assure you that I am correct, there is no way a krell amp is going to work without a dedicated line!, The amp draws to much current!, LOL!, I tried that once with a krell fpb 200, you should have seen the bulbs in the house flicker and some blew, and guess what, the amp would shut off to stand by quickly!, how do you know the op has a 15 amp breaker now?, If he does, LOL!, thats a 15 amp breaker for a room or two rooms in the house, not a single receptical that his amp is plugged into!, regardless, I hope we can help the op here,I have 18 years of exsperience with krell amps!, The ONLY krell amp that I could ever run on standard house wireing receptical was a krell 300I intergrated amp, everything else had to have a dedicated line with a 20 amp breaker to work!, the op can use a 20 amp breaker for his krell ksa 200s and still work, His problem is he cannot share power to the amp with anything else!, cheers.
