i have the same issue with my spider iv 120, i purchased it around two years ago, the fault originally happened within a few months of buying it, during a few gigs it was cutting out for a few seconds then returning back to full volume then cutting out again...so frustrating! therefore i got the shop to send it to line 6 for repair. The same issue has now started happening again, and now i am unable to gig with this amp as it is now out of warranty and totally unreliable (good job i have my peavey backup).i will not be wasting my time with a repair centre as i think line 6 should take ownershop of these issues as this is a commom fault by reading this thread. Im bitterly dissapointed with line 6 and this week i will be looking for a new amp something non-line 6 due to my bad experience with this amp. what a waste of money!!!

Nah, I don't think its a tube issue. The amp doesn't shut off, blow a fuse or do those normal tube failure things...it "resets" and during that reset time, you have no sound! The amp doesn't turn off.

I have a SV HD100 MK1 that did exhibit this when I used it for a bar gig. Late in our second set it would cut out, and seemed to reset. It did this repeatedly until I turned it off and went to my Crate Powerblock as a backup. I let it cool off during a break and it worked for most of the 3rd set before it started the shananigans again.

When I posted about this, I was told it was probably the venue's power, but by using it several more times in similar situations, but different venues I am quite sure it simply overheats and resets. I also have a MKII head that hasn't done this, so I have no idea if this is only happening to a certain number of amps, or what. In any event, I have another show coming up which is small enough to warrant using the Line 6 rig so I am going to get a fan and see if that helps. But I'll be ready with something else when/if the Spider Valve takes a dump.

This is a tube amp.

Being as the problem occurs when the amp is "hot" (although this 'matters not'), the solution is simple. Tubes.

Your duet/quad is either mismatched, or one or more tubes are crap. Instantaneous breakup would be much more evident if the ordeal was in the pre section.

Moral of the story: PROCURE GOOD TUBES! MATCHED quad or duet ALWAYS. If you don't know how to bias, do some homework... or take it to any reputable shop, for they know how.

Preamp tubes are important as well, but they won't cause a catastrophic failure. Most people are unable to ascertain the simplistic nature of simultaneous analog/digital operation; and with that said, bad power tubes will most assuredly send some type of bogus voltage down... and this is bad news. Perhaps it's why Line6 won't (and shouldn't) be responsible for repairs that arise from horrible or old tubes being used. Especially for long periods of time.

My advice is to use only JJ/Tesla, Mullard, or Tung Sol (for preamp).

Thats easy. Not our problem. Pay to fix it, or buy another amp. Have a nice day.

Hey Guys,

So what are the Line 6 Service centers saying about this problem?

Tom,

i have recently had the same problem with my Line 6 valve 100w head. I have also discovered that by pointing a fan or other cooling system at the back of the head, it stops the problem. so what i get from this is that the head itself is getting too hot and needs better cooling. anything will work, i just used a swamp cooler without the water in it, no problem after that. So try getting a small box fan, or a desk fan and put it behind your amp.

hope this helped

Eric

I bought a 1-12 as they were being discontinued and it is doing the same thing, no fbv board to plug in. Seems to be heat related, does it after it has been on awhile, if i point a fan at the back of the amp, it will straighten up in a few minutes and be allright, as long as the fan blows

going to see about getting it fixed soon, still under warranty

I haft to diagree on the design problem statement because there are so many amps that work good, and mine is one of them. 1 3/4 years so far without any problems.

I have heard of a voltage regulator problem that is more of a component issue then a design issue. Some amps have this issue where most do not. You are having bad luck because it didn't happen to your amp until the warranty ran out, or you let the warranty run out without getting the issue promply repaired. Now the fix will be on you. For the good or for the bad, I'm afraid.

Take your amp to a L6 authorized service center for repairs or scrap it out for parts. Other than that - there is not much you can actually do to resolve this problem. Sorry to say that, but its more or less true.

Good luck guys

It seam's like a common problem.

I would have to agree, there's a possible design problem with the DSP chip board overheating.

Is this a known issue for Line6? I have seen several blogs where people all around are having the same problem. My amp is also having the same problem, it keeps constantly shutting off after playing more than 30-45 minutes. It is like the electronics are overheating. I had this amp for about 2 years, and now is just laying aroud because it gets annoying to play it. Would Line 6 take care of it, or do I have to put my money in for your bad design?
