if you blew a fuse -- or anything else that quickly either you have a coincidence, ro, i suspect, you shorted something liek a speaker wire, and that short likely is still there. Check carefully. In fact begin withe the speakers disconnected. if you hapen to own a VOM, with everything off, and ideally, but not reqyired, with the wires disconnected form the amp (its off, right? and has been for a long time, right?) measure the resistance across the speaker terminals.
I think I just smoked my Amp
Ummm… yeah… what the title says…
Just received a new pair of speakers, Thiel MCS1. I got them hooked up, powered up my pre and my amp, started playing a test track (a progressive house song), I immediately noticed a slight crackle in the right channel, and as soon as the song got to the part where the bass beat dropped, the amp went into protect mode. It stayed in protect for about five seconds, then the “operate” light came back on, but the audio did not return. I powered the amp down, tried powering back up, but the protect light immediately returned, but it was extremely dim. Now, the power switch does nothing; nothing lights up. I smelled the vents in the top, and nothing smelled burnt or out of the ordinary.
My uneducated guess is that the lower impedance (4ohm nominal, 3ohm minimum), strained an aging cap which then gave up the ghost, but really I have no idea. My previous speakers were a much easier load (10ohm) and the amp handled them just fine.
I really don’t know what to do now, but I’m bloody devastated.
My system:
ARC LS25 MKII
ARC D400
SMSL M400
Auralic Aries

i lso dont think the discussion on 2 fuses above sounds right. You almost certainly have one line fuse on the 117 VAC (house power). Other fuses woudl either be rails (+ and - power supplies) or speakers. Both are in pairs. So i can see 3, btu not 2. If there are really two , i suspect both are power/lie one for supervisory o similar power and very small. |
Thanks to everyone who took the time to respond. The status of my D400 remains unchanged. Visual inspection didn’t reveal any possibility of shorted speaker cables. I spent most of the day driving to retrieve my CODA amplifier from storage; maybe I should store my things closer to where I actually live 😐 I’m going to figure out how to open the case, and run down those fuses. @bigkidz I appreciate the offer, but am located in Oregon, and trying to avoid shipping this amp if at all possible (no original packing materials). Coincidentally, my speakers were shipped from NJ.
