Can i use a 250v 4a fuse for my cerwin vaga speaker even if its not a slow blow and what could happen if i did would it damage the speakers


If you're replacing the fuse with the same specs and the only difference is the new one is not a "slow blow", you won't damage the speakers, but the fuse could blow again even if there is no actual fault. The slow blow is designed to accept a temporary surge of power without blowing - as in initial power up.

Internal damage to Mirage BPSS-210 Subwoofer amp


Something getting hot probably means something shorted out. You probably know that since you replaced the fuses already... . Can you give me some idea of what you do and do not know about electronics? Then I will say fewer dumb things. . When troubleshooting any electronic device, especially amps, open it up and look at the circuit board. Look for burned board and components. Then test to see if the burned/blown component had reason to blow (it probably did). . Often a shorted transistor runs too much current through some other component and the other component blows up. . Another cause, less common, is a shorted cap. . Look at the schematics if you have them, if not, you may have to create one to make sense of it. . Or take it to a shop where somebody does this all the time. The only one here went belly up in the last 12 months... . . About the pots . Try blowing out the pots which are popping with some tuner cleaner. Use with caution, and always with everything turned off and power cords unplugged. . Pots do not usually make popping noises unless they are very old or live in a very dusty place... . I found the manual, but no schematics... http://docs.google.com/viewer?a=v&q=cache:9Doi39-AcW0J:www.miragespeakers.com/images/download/374.aspx+Mirage+BPSS-210+schematic&hl=en&gl=us&pid=bl&srcid=ADGEESjBKgLSTb8wp5SRWIOWd-gE0INdBXbfz5QDNJ_3esye4_R2Q9aKba8cEePSWQWOebeXB9zXnJSelIel2bLSR5q6KExe8MVjOk1zqFKk4K-ruti_797yf1Ig3CIcUNjE49jx8DAr&sig=AHIEtbS6udedt_o6GqL7ALPunU0v3vMvuw . You might be able to get better, more exacting help on the Mirage Forum... http://community.miragespeakers.com/forums/ But maybe not, since the Subwoofer section gets less than one post per month, and the much busier Technical Questions section only has 23 in the last 12 months.

Fuse blows


Both 3 or 4 amp slow blow fuses are suitable replacements for the 3.125 amp subwoofer fuse.

It could be that the subwoofer is blowing the fuse because the one you installed was not slow blow.

But, more likely is the subwoofer has a short in the power supply which is causing the fuse to blow.

Fuse keeps blowing?


The fuse is a protective device. Fuses dont blow unless the amp ( in your case ) is drawing too much current. DO NOT put a bigger fuse in. Obviously, there is a problem with the amplifier inside the sub. If the sub is under warranty, send it in for repair to an authorized warranty depot. If not it's not under warranty, then take it to the authorized warranty depot anyway. Why ? because they will have the schematics ( electrical diagrams ) to troubleshoot the unit quickly and it may be a common problem. If it is a common problem, the factory may have released a modification and possibly it could be covered under warranty under a factory 'goodwill' program. Good luck. Rob

Repeated fuse blowing generally indicates a blown power supply, or blown output stages or both. One thing to do is be sure that you have replaced the fuse with the correct type. A T stamped into the metal of the fuse near the rating, indicates sloblo or Time Lag fuse. A fast blo fuse, may work once, or more times, but will never replace a sloblo fuse in this type if unit. Good Luck, hope this info helps, don't hesitate to hit me back here for more help :)

M-Audio BX8 blows a fuse


If your monitor is crackling and fizzing, that is not a fuse issue, unless the fuse you have installed is underrated. It sounds like you have a bad driver/woofer, and need to get it replaced. CLICK HERE FOR THE REPLACEMENT DRIVER for this model.
