Hehe , this is an interesting one , well i bought myself a warwick tubepath 5.1 and in all its amazing!!! butttt when i turn it on it has a funny smell to it from which seems to come from where the tubes are placed. the smell is a bit funny , its similar to that that comes from a photocopier when your copying paper. Im a newb to tube amps so if this is me bein dumb lol tell me!! the amp works fine by the way and the casing is cold to touch and the fan is workin fine and it was played pretty much continually last night for about 2-2.5 hrs and didnt burst into flames.
