I have a Denon PMA-360 integrated amp, rated at 50 wpc. Got it for free from some punk kid because "it was so old, so it could not be any good. Look, it even has theese stinkin´phono inputs!". But it worked, it sounds very good and is well built. Even the front panel and knobs (except the input selector and push-buttons) are made of metal. There are two speaker outputs and input for aux, tuner, cd, MM and MC phono and in/outputs for two tape recorders. The circuits are mostly discrete, but there are a few ICs.
