Is my Amp toast?

We were setting up for a gig Saturday night and the lights went out on my head earlier that day there was a sort of bang/crackly noise heard by the drummer... but it still seemed to be ok, and there wasn't any burnt smell like I'd blown a valve..

taking it in to the rockshop tomorrow, but any bids on what sort of damage I'm looking at? Its a Peavy ultra 100w head.. a sad day indeed!

Forums: The Bar,

Have you checked the fuse(s)?

whats peavy ultra like compared to a hardcore max? Sorry for not actually answering your question :P

the fuses aren't clearly labeled on a box sticking out on the backside of the amp so I have no idea :) But you could be right, I hope its just a fuse,

Trade in that ultra head for a 5150 and bring teh chug.

I tried a 5150 amongst others like laney and Marshall and honestly I love the Peavy ultra sound, but I've got a Marshall JCM900 quad, I have no probs with my sound/amp, I just want to fix it,

thanks tho, 5150's seem to have a lot of fans!

I've never been overly keen on peavey, personally I find they sound a bit thin and nasally, but from the sounds of it you've probably blown a fuse.

Get rid of it ASAP.

try laney they make nice sounding reliable amps in a mid price range.
Also part of the problem may be the size of the head, generally speaking 100watt heads were designed when PA systems weren't as versatile and amps needed to be able to power out a stadium with out being mic'd, get a 50 watt head instead, it'll still be plenty loud enough and you'll fing it'll sound great because instead of running your amp on idle you'll be able to crank it up more and get the valves working properly.

Valves don't start really coming alive untill the amp is cranked, so your 100watt is probably choking itself to death.

Could be a fuse- especially if you guys were just setting up/plugging things in, etc.
Fuses can be funny things though-
If the fuse blew properly, then with a new fuse you'll have your amp going again in no time.
If the fuse was a faulty one, and did not blow under the load it's rated at, then the power surge might have caused some damage to your amp. $$$$ (unless you have a warranty).

PS: don't listen to these guys telling you Peavey don't make good gear, or that you need a different amp or less headroom or whatever. You can most amps sound however you want them to sound, you just have to know what your doing. Most amps make great sounds. All amps are succeptable to fuse blow outs.

Hmmmm ... nearly ....

Fuses are used to protect the equipment in the event of a fault in the equipment. In valve equipment, as a general rule it the HT fuse blows it is an indication that the power amp valves are likely on the way out. Replacing the fuse will probably get the amp going again but if it blows again after a little while it is a good idea to get the valves checked out. If the amp is still under warranty get it back to the retailer. Otherwise ask around to find a techo who understands valves.

If the fuse just blows the once, particularly at power on or power off then chances are there is no major probs.

Point to note, particularly for those who live in older houses, if the fuses keep blowing for not apparent reason get the wiring checked out by a reputable sparky. And having too many applicances hanging off a circuit is never a good idea ... this safety tip brought to you by the Acme Fuse Coy and ...

There you go- cheers Stu!

thanks for that, unfortunately I've had it for about 5 yrs, so no more warranty! I'll see what the quote says
