I use to have a Krell FPB 200 and the manual "Recommends" a 20 amp circuit. My house was built in 1997. Most to outlets a 20 amps. When starting up the Krell, the lights in my listening room would dim for the second. It was a me issue, I had too many devices on the circuit. I put in a dedicated 20 amp.
Advice to original poster: 1. Call Krell. 2. Locate and trace the power circuit, unplug all the devices on the circuit, then test the amp.
