Peavey 6560 problem.

[Sam Laming]

We turn it on and the tubes don't heat up/turn on, it's my guitarist's in my band, he's going to call Peavey soon but just woundered if any of you may know the problem, it's really bizzare

If a fuse is blown, that most likely means one or more tubes died. When people refer to a failed fuse as being "the problem", that doesn't make much sense. Failed fuses are only a symptom.

True - but it could have been as simple as a voltage spike popping a fuse and replacing that fuse "might" fix the problem. Of course if it does fix it and it blows again, it's time to start checking tubes. It's not been my experience that tubes just flat out fail all of the sudden, they usually start making funny noises or start sounding dull and less loud - and then they die. Even if the power tubes start red plating, it's usually just one of a pair that's crapping out and you'll hear it before it melts down and takes the amp with it.

Just my .02 - YMMV

Randomly it made those 'tubes are dying' noises once or twice then works for a week or two and only now have we had this, he's taken it to an amp repair place though so we'll see what happens.

Thanks for your help guys

I think fuses and tubes get thrown out there a lot from non tech guys because it is fairly safe thing to try since most of us have extra tubes or fuses anyway. Beyond that it involves a trip to see a tech for most of us. Plus if it is anything like around my area the amp could be sitting for a few weeks before anyone even looks at it, and may find out it was just a tube anyway. So I guess I am answering why I have suggested tubes in the past. Any amp advice I give is usually followed up buy I am not a tech or I am not a tech but when it happened to my amp it was this

One could argue that a bad tube is the cause of a fuse blowing and a fuse blowing is the cause of "no sound." Just sayin...

Always gotta make the point for the other team don't ya?

He he... I tend to overanalyze things.

You do? So did you fall in love with the UL or not? I couldn't really tell for sure.
