Serious Power Problems with my HPA2


Hello all
I bought a proceed hpa-2 and im having some power issues that i nor anyone else ive ask can answer. The Proceed amp goes thru several checks when you turn main power on and if it does not like what it sees it goes into protection and wont let you turn on standby power. With the amp plugged into just the wall no inputs or spk cables connected (but yes i have tried it with those connected) the amp at my house goes into protection. my volt meter says i have a fairly steady 121.9 to 122.5 vac. if i leave the amp on the floor and run an extension cord to my neighbors house the amp powers on fine every time. I checked his voltage and its in the same range as mine. I have turned off every circuit breaker in my home and ONLY connected the amp and still have the same problem (its a 20 amp circuit) ive called the power company to come out and check the power (they say its fine) and called an electrician to come check house wiring (he says its fine). What am i missing? is there any power device that would solve this problem that can handle the current draw of an hpa-2? Does anyone know anything about the problem im having or can you offer any ideas as to why this is happening?
Please help as im out of ideas
Thanks

Good idea Gmkowal , but Since it is so heavy, you might also try to use the extension cord on your outlet. Do you have another power cord you can try? Maybe there is a problem there and it was just turned the right way when plugged into the neighbors house? Although you would think that would trip your house breaker. My lights dim a little bit when I power mine on but haven't had any problems except staying up too late to listen. Let us know what you find out.
Have you tried to contact Madrigal yet? If you purchased new from a dealer you might want to contact them also. Have you tried to power the amp from another outlet in the house? I would think the electrician would have checked this, but make sure the ground is good to the house. You can buy outlet checker, I think at Radio Shack or Lowes. Also check the voltage with a load on it and see if it drops. Hope you get to music soon.
