I bought my first CAMP-1 amplifier from Apollo 2000 but when I got it home, it was totally dead. I returned the amplifier and agreed to take another one. When I got this one home, the right channel switched off after ten minutes of continuous use. The case was quite warm on the right hand side so I guess that there was an internal fault. I returned the amplifier to Apollo 2000 for a complete refund. This is a cheap unit, which shows from the general standard of design and construction and lack of proper testing. The amplifier (when it was working) was under-powered compared to my twenty-five year old 50-Watt Realistic amplifier, which I am still using until I find something better!
