Hot Rod Deville 212 -- Blown Fuse

Phranklee · 01-09-2009, 01:46 AM

Hey everyone. I just got back from a three week vacation and turned on my amp. As soon as the red light came on the amp popped and turned off. Nothing would power up -- no lights, no sounds, no anything. A fuse was definitely blown (I took it out) and I'm wondering whether I should just replace it myself (3A 250V) or bring my amp to a shop. Is it possible that the fuse just blew on its own and there's no deeper problem (bad tubes or anything like that)? If there is a bigger problem, could replacing my current fuse and blowing the new one make the problem even worse?

The amp is between two and three years old.

Thanks for any input!

Fuses don't blow on their own. Something made it blow. I would check the output tubes first.

But by all means try another fuse. Most common reason for fuses to blow is a failed power tube.

Hi there,
I've owned and gigged a Deville for about 12 years now. I replace my power tubes about every six months, which has cured the problem of turning up at a gig, turning on and popping a fuse because a tube is shorted. Take out the power tubes replace the fuse (if your supply voltage is 230 then the fuse is 1.6 amp, 3 amp for 110v) if the amp will come of standby without blowing the fuse then you have a bad tube.
