B&K 200.5 S2 Power Amp problem - Please help

I had a 7250ii (200X 5) and a 2500 (60 X 5). They had a slow blow fuse, but when it went, nothing worked. Radio Shack may have one, but I think I got mine from an Automotive shop like Autozone or Checkers.

It sounds like the vloume knobs in the back, but it not are you getting a Hum or buzzing sound as well, it so that could be a ground problem with the RCA inputs, they can get dmg during shipping.

Hope this helps.

According to information on the B&K website, they are working on a solution for warranty repairs, and that owners should contact the following e-mail address for technical support: george@ee-av.com

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!

since you have power you definitely don't need to worry about the main fuse (15 amp), and likewise you have some sound so you don't have to worry about the speaker fuse) The Rail fuse is a 6 amp Slow Blow with 250 volt rating (6A SB/250V)

Here's the fuse you want - they have them at radio shack:
6 amp Slow Blow fuse

How does your amp sound other than it's not loud? If the rail fuses were out, I'm thinking you would have worse problems than low volume. I also wonder of the volume pots are somehow inside your amp.

Did you compare your amp sound to your friends in your system? If not, your perception may also be resulting from your pre/pro setting.

First, all your fuses would appear to be 'good'. You ARE getting output from all 5 channels, right?

Look at the back panel. There will be a balanced / unbalanced switch near each set of inputs. IF you are using RCA connections, make sure it is set to 'unbalanced'.
Turn the level way down...or the system OFF before adjusting this.
I'll bet the last owner used balanced connections and it is so adjusted.

Also, how sensitive are your speakers? I can't believe that is the problem, but it never hurts to ask. This amp should even drive my low-sensitivity panels OK.

I read the instructions:: no level controls inside the amp.
