Behringer Ultratone K3000fx 300w

SOURCE: I own a Behringer Ultratone

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:

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.

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.
