Question about Ashdown Klystron 500w Bass Amp Head
The fuse blew because of excess current. The cause of the excess current is either excess volume, a short in the speaker, OR the amp has failed and is shorted to one of the power rails internally and is driving DC current out.
Replace the fuse and use a meter to check the output voltage with NO speaker connected. It should be under 1/2 volt period. If it is, then check the resistance of the speaker. The DC resistance should be a little less than the rated impedance. Otherwise if the amp is kicking out a higher voltage or blows the fuse again, have the amp repaired.
