Often they will just double up with two amps, one inverted, and use in bridged mode.at the higher power in what we call an "H" arrangement.

Since the drains are tied together, the heatsinks MIGHT be hot output level.

This is most LIKELY an electronic problem... possibly in the final power amp. Repair may be a simple failed component or a mass number that fail like a stack of dominos. Take it to a shop for repair.

Here is your service schematic:

http://elektrotanya.com/behringer_k1800fx.zip/download.html

Scroll down to "Get Manual" and click on it to download. The file is compressed and the preamp/FX is on one, the power amp on a second, and a trivial tweeter crossover on the third... I did not see the power supply. Check speaker for continuity of voice coil. Else it is likely a power amp failure.

Something blew during a loud performance and now it produces continual high-freq feedback that can't be controlled.


The speaker may be blown, but if you're getting continual Hi-freq feedback that is not resolved by lowering the volume know, you need to take this to the repair shop.

Where can I get a Type T 6.3 AH 250V fuse for a K3000FX 300Watt Keyboard Amp?


Start with a 5 amp fuse and see if that holds. If it doesn't go to 10 amp. If that pops, you will have a power supply or amplifier fault. Good luck

For a start , check headphones out.

But check the main volume .

Will an Eminence Beta 15A speaker (`5", 300w, 8 ohm) fit/work in the k3000fx? If so, will there be a trade-off or consequence of performance? I already own the Beta speaker, and have a chance to...


It ill probably work, however I have had to do body-and-fender work on a speaker cabinet where the new frame would not quite set in the existing hole in the mounting board. The Eminence speakers are supposed to be good... are you sure the Behringer amp is OK? The K1800FX uses a conventional linear amp... not sure about the K3000fx... The only possible problem I could see is that the original speaker (Bugera 15 inch)may have a different response and the tweeter may not match too well. You can probably adapt using th EQ should this be the case.
