B&K 200.5 S2 Power Amp problem - Please help

Hi guys,

I need your help and advice please.

I purchased this power amp on Ebay a few months ago. I just realized the amp is having a problem after I heard my friend's B&K 7250 version II (old model). My power amp, all 5 channels, has had low output. Is that possible that my power amp blows the fuses? If yes, do you know where can I buy them? Since B&K company was taken over by ATI company recently, it's hard to contact them for advice.

I'm really appreciated for all your help & advice.

Thanks!

I appreciate all your information and suggestion.

Bdgregory - Yes they all have a low output at the same time since I purchased them on Ebay. At first, I did not realize it. After I had a chance to listen to my friend's B&K system, I found out something wrong with my amp. My amp does not have the volumne knobs on the back, so I could not do anything else. Can you explain more the fuse number below?

Main(Line) - 15A SB/250V
Rail (internal) - 6A SB/250V
Speaker - 6A SB/250V

If I go to Automotive shop per Briweve's suggestion, what information I should give or ask them? Sorry I'm blind with this.

Briweve - Again, my amp does not have the volumne knobs on the back. I turned the volumne of my pre-amp to 90%, there's no HUM OR BUZZING SOUND from my speakers.

Gbart - I emailed George, but I have not received any reply from him yet. Also I tried to contact the seller and hope he can response back and help me with it.

Thanks again guys!

Magfan - You're right. Last night, I changed RCA/XLR switch from XLR to RCA and the output volumne increased. I thought the amp won't have any sound if the switch does not setup correctly. My bad!!!

Anyway, thank you so much guys for all your help and make my life happy now......
