Go to Head-fi if you want to read the trail of tears about Singlepower. Many, including myself, have axes to grind of various sizes. Some people bought Singlepower amps that they recently learned have substantial design/manufacturing flaws. Some have done the repair work themselves, others have had the work done by a tech, others have been told their amps cannot be salvaged at all. Others were the victims of worse fraud -- they paid for Singlepower amps either in part or in full and never received an amp. The owner of Singlepower, Mikael Rotenberg, simply disappeared with their money.
Before Singlepower was revealed to be scamming customers and sending out poorly built amps, the brand was held in fairly high regard. My advice is to get your amp checked out by a tech to make sure it is not dangerous to operate, since that has been a concern raised on Head-fi. I have yet to hear of anyone being electrocuted by a Singlepower amp, but there is always a first. If the repairs are inexpensive (a couple hundred bucks), get them done and enjoy the amp. If the tech says the amp needs substantial work that will cost a lot of money, I would just ditch the amp. You might as well buy something with some resale value, because the market for Singlepower amps is non-existent. You cannot give a Singlepower amp away these days, since everyone assumes they are time bombs waiting to explode.
