Review on Pyle Home Mini Audio Amplifier - 60W Portable Dual Channel Surround Sound HiFi Stereo Receiver with 12V AC Adapter, AUX, MIC IN - Supports Smartphones, iPhones, iPods, MP3 Players - Ideal for 2-8ohm Speakers - Pyle PFA200 by Lisa Carter

Contacted Pyle to replace a defective power supply under warranty and received no response. They are willing to sell me a new one but don't answer if it can be replaced under the manufacturer's warranty. Update - The power adapter is an "accessory" and is not covered by the warranty. They gave no advice on how the receiver could work without power. Now I have to ask for an additional warranty to see if it covers the faulty PSU. The product works when it has power.
