Tandberg 3012 - Hot fins


Hello guys,

I recently stated using a vintage Tandberg 3012 integrated amp and noticed that the cooling fins located on the left side of the amp in the area of transistors (4 each) gets very hot (almost to hot to touch). The amp works great and sounds superb but I am wondering if this heat issue is normal or if it may later become a problem or is indicating that something is soon to fail. I used the amp this winter with a cooler room temperature and the heat in the reported area was definitely not as high. I just want to know if this is normal for this amp.

Thanks,

I am using it with Proac 3.8 speakers at low levels (I hate loud music). This winter, I was using it for a couple weeks with Proac 2 speakers. I will be going back to my CJ MV60SE amp soon. I am just playing around with my equipment.
It is a 3012, not a 3012A. Dust was cleaned out. Everything is balance and it sounds really good.
I will go back to my CJ MV60SE amp tomorrow. I think that you are correct in that the 3.8's are a bit much for the 3012.
I did not want to take a chance and pulled the 3012 out of my system. I will try it again in the near future with more efficient speakers (vintage Dynaco A25) and see if it gets as hot.
Are you pulling my leg. How would you adjust bias on this S/S amp? Can this be done by anyone with technical skills or does it have to go to a repair shop with specialized test equipment?
