Mr. Foxen Posted March 15, 2009 Share Posted March 15, 2009 I was given an Electric Blue 150 that had no output. Fired it up, gets input, but no output. So I plugged the speaker part into my other EB-180 combo's output, and now that one doesn't work either. Guess its the speaker shorted or something that kills amps. Am I likely to be able to find a fuse to replace that will fix that? I've mailed Ashdown tech support. Quote Link to comment Share on other sites More sharing options...
Alien Posted March 15, 2009 Share Posted March 15, 2009 Sounds like the speakers voice coil has gone short circuit. Never owned an Ashdown, never looked inside one, but it'd be pretty remiss of them to not include a speaker fuse on their amps. If you've got a multimeter, check the continuity through any fuses you can see inside (for gods sake unplug everything first!) Any fuses that have a resistance of more than a fraction of an Ohm are knackered. Andy Quote Link to comment Share on other sites More sharing options...
Mr. Foxen Posted March 15, 2009 Author Share Posted March 15, 2009 I can see a blown fuse in the original one, Gonna take that speaker out and shoot it also. Hoping my combo is the same with a fuse, since I'm part exing it for a Acoustic combo. Quote Link to comment Share on other sites More sharing options...
josh3184 Posted March 15, 2009 Share Posted March 15, 2009 shooting it is not going to help anyone Quote Link to comment Share on other sites More sharing options...
Mr. Foxen Posted March 15, 2009 Author Share Posted March 15, 2009 Took the speaker out, problem was the two wires going form the terminals to the coil were touching (themselves at night). Pretty textbook short. Off to Maplins for fuses after work tomorrow then. Quote Link to comment Share on other sites More sharing options...
josh3184 Posted March 15, 2009 Share Posted March 15, 2009 thats a bit of a bargain amp then! Quote Link to comment Share on other sites More sharing options...
Mr. Foxen Posted March 15, 2009 Author Share Posted March 15, 2009 As far as I'm concerned, bargain equipment is the only equipment for me. Rapidly looked like it wasn't a bargain when it killed my own amp, which is about the only theng I've ever bought new, will have to see if fuses fix them.

Chances are there's nothing wrong with the speaker if the leads shorted. Pretty unusual fault though - usually the tinsel leads are set far enough apart that they can't touch even at maximum cone excursion.

A[/quote] Well, there was plenty enough slack on these for them to touch, they were touching when I took it out, and there is that residue on them you get when things are sparking. I taped round them and stuck the tape to the chassis, hope it won't touch the cone and make noise, shouldn't do. Quote Link to comment Share on other sites More sharing options...
Telebass Posted March 17, 2009 Share Posted March 17, 2009 Good luck with that, nice freebie! Do tell how it all evolves. Quote Link to comment Share on other sites More sharing options...
