Serious Power Problems with my HPA2

thanks for your reply although i didnt carry the amp to the neighbors house i did try to run it thru the extension cord at my house and i tried several different power cords with the same results. my concern is that i box this thing up and send it to proceed and it works great there so they send it back to me still broken. still seems strange that it works on the neighbors power.

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.

I would also check to see if the hot and neutral wires have been reversed at the outlet(s) or at the junction box, or that the ground wire is not properly grounded. European electronics typically have more stringent power safety regulations. If any abnormal condition exists, the equipment won't function. Goodluck.

may not help...but I have an HPA3 and a levinson 334 in my hifi room...all running on the same 20 amp circuit...although conditioned through Tice power supplies...this 1 circuit also has my RP TV and the sub...seems like it would be localized in the amp....

good luck

Try one last thing before you box up your amp and send it away. Jctubes has a valid point about neutral and ground being swapped. I understand your electrician had a look, but nobody is totally infallable. Lord knows there have been a hundred or so times that I have caught myself after a second look. Go to your local hardware store and for maybe $10 pick up an outlet tester. This is not a test light but an outlet tester. The tester usually has 3 small lights on it. If you plug it into your outlet and it is wired correctly a certain sequence of the lights will light. If the outlet is wired incorectly a different sequence will light and the sequence can be decoded to determine exactly what is wired wrong. This inexpensive tool should be in every audiophile's toolbox. I also recommend if it checks ok to plug your amp in to one of the plugs and the tester into the other to test it under a load. I have seen a few instances where resistance in the ground path to an outlet has caused a problem and this can only be found when a load is placed on the circuit so current is drawn. The tester should be able to pick up this problem also. For less than $10 it is worth a try and if you do find something please don't blame your electrician as nobody is perfect and everybody has an off day now and then. Good luck.
