Rogue 88 problems


I bought an used Rogue 88(not magnum). I met couple of problems, hope somebody could help me out.
1. The fan gives rather big noise. My listening room is small (13X12), and it's really annoying. The seller told me the amp is about a year old. Is it about time to change the fan?
2. I hear sparks from the speaker in the first 20 mins when I turn 88 on. What could be the cause of this?
3. This one is not really a problem. When I switch from UL to triode, the volume of sound dosen't change. I am expecting the sound to go down, because the output is half of UL.

Thanks in advance.

A Bob Crump DIY is all you need to get this thing sounding great.
Any more spent and its a waste.

no more that 5% of your budget should be spent on cables.
Why make comments thaat are not true. I ran a Rogue 88 for over a year with the fAN DISCONECTED.
Th 120 have double the power of the 88. 120 Watts vs 60 Watts I belive. Did you listen in Ultralinear or Triode. Triode on the 88 is 30 Watts, I used them on a pair of 92dB speakers with great succes, then got 120 and Know the 150.
Last amp I will need.
