Thanks for your suggestions. I brought back the amplifier to the store where I got it and they agreed to fix it. The problem was that they put the wrong tubes in the amp which was a 12ax7 (i think) instead of the 12dw7 or the equivalent. There was also a cold solder joint. They replaced all the tubes and it is now working perfectly so far since I got it back this afternoon. There was no smoke but I thought at first there was a funny smell of something burning or heating up.
The amp sounded pretty good and I even did not expect the bass to be that well because of some reviews that I've read. I was just using the speakers of a sony micro system.
I'm just wondering whether the amp really gets this hot, that is, the cage especially the area above the tubes get a bit too hot to touch after 10 to 15 minutes of playing.
