What happened to my SET amp?

Hey all,

I was playing my Dared 845 SET integrated amp today, and after about 10 minutes, I noticed it had quit playing, the power lite had gone off, and it was smoking like hell from the lower-back of the amp. I pulled the fuse at the IEC and it was blown (thankfully!). It was marked as 125V/8A.

Nothing has changed since I've originally hooked it up about a month ago and it has played properly for hours at a time since then.
Any ideas what might have happened?
I appreciate your comments.
Good Listening!

Possibly either a temporary power surge or that any of the power tubes are or are going bad.

I'd suggest a call to Dared and tell them what happened. No sense replacing that expensive 845 if it was just a house power glitch, and even pulling a tube to test it may violate a warranty.

Pulling out a tube will violate a warranty? "Expensive 845"?? HELLO??

Do you have a backup pair of 845s? The stock Chinese ones are around $60/pr.

If you replace the fuse and try it again, worst thing that can happen - probably - is another blown fuse.

If it was smoking, a fuse will NOT fix it. A shorted tube can take out a resistor, etc and you have at least done that. The smoke could also indicate an expired capacitor or(hopefully not)shorted power transformer. Don't waste a fuse. Get the amp serviced, if you are not competant at electronic repairs yourself. Should you choose to open the unit and assess the damage- keep in mind there may be some very high voltages stored in the power supply caps.
