Blown Speakers from a non-functional amp?
Greetings all, long time lurker here, this is my first post. I've run into a problem that is just about the weirdest thing I've ever seen. I searched extensively, but I can't find anything on this.
I bought a new (to me) Eden WTB1000 off of ebay last week. It arrived yesterday, and I took special care setting it up correctly, even following the instructions in the manual! I use two GK 410's, one for each channel as I use stereo effects.
When I went to turn it on, nothing happened. Literally NOTHING; no lights, no sound, no fan, no indication that it had powered on at all. I double checked everything: connections, fuse, cables, I even tried the removable power cord on another amp of mine and it fired up no problem. Needless to say, I was extremely dissapointed, so I sent the amp back.
Now here's the kicker:
When I set my old rig back up, (two ampeg SVT-400Ts) the bottom right speaker in each cabinet was blown! I don't know what could have possibly made this happen to both cabs simultaneously as they were perfect before I hooked them to the Eden. Once again, I checked all the connections, even hooked them up to another amp, and they still sounded blown?
Has anyone ever experienced anything like this, or is there something I'm overlooking here?
Did you find the internal fuse in the Eden was gone? Speaker blowing should make some noise, an already blown speaker killing an amp probably would make noise too.
The Eden probably sent high voltage DC from it's outputs and fried your speakers. The lights probably didn't come on because they may have been blown already.
The amp comes with a replacement fuse; both fuses appeared normal. I tried the replacement as well to no avail.
From what I understand, DC light on the front should come on when the amp is engaged. It also states in the manual that it is safe to run the amp with no speakers (for practicing with headphones) and that didn't work either.
The speakers still produce sound (albeit crappy) with my old amps, so it seems like I should have been able to hear something if the Eden were at all functional. I just don't understand how my speakers could've been damaged if the amp isn't working.
Welcome to TalkBass os mutanto.
I haven't worked on Eden amps, but it's entirely possible to have either of the rail voltages present in the speaker outputs without any of the indicating LEDs or indicators lighting.
Edit: Just to add, since it's DC that's fed to the speaker, IME all You hear in that case (regardless whether it's the case here or not) is a thump or a click as the driver bolts onto either of its excursion extremes, and eventually fries its voice coil if the power is adequate.
