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.

Pren,
I have the 88 for about 2 yrs now. When I first bought it (new) the fan was audible from 8-10 feet away. I sent it back to Rogue who swapped it out and now I cannot hear it.
I have found Mark O'Brien to be very responsive to customer inquiries so you might contact him directly at Rogue. Len

Well. I have to add this. I had my Magnum 88 for 9 months like I said earlier. I tried everything to make it sound the way I expected it to. Cables, tubes, power cords.
Well I just got my M-120 Magnums. There is an amazing difference between these 2 amps. Finaly my system sounds the way I thought it should after spending many thousands of dollars. Unbelievable, It is like I replaced the whole system. If you ever get tired of the 88, give the M-120's a try. You won't be disappointed.

on a side note
has anyone had any good/bad experiences with different power cords and the 88?

I use an Audio Magic Illusion power cord on the 88 with great results. The sound is more expansive, for lack of a better word.

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.
