AMC makes tube amps which I believe are designed in the UK and made in the far east. Their list prices are not much to get excited about, but their gear seems to be highly discounted, especially on ebay. I could not resist this situation and bought their model#cvt2100 which is an 80 watt tube amp using 4 kt88's for $700. It sounded fine, very similar to Quicksilver Mono's that I also own. It was a little more forward in the midrange than the Quicksilvers but it had more extended high's and lows. The only negative I could think of was that the amp had fans and I could barely hear them during quiet passages. Also, because of the fans, you need to give the amp some breathing room. The amp turned on and off with no funny noises and the tubes will probably last a long time due to their being fan cooled. Resetting the bias after changing the tubes was a little tricky-probably best left to a technician.
