Hey guys,

Okay, I'm pretty sad right now, because I think I blew my amp. The sound keeps fading, full distortion is only a tiny overdrive, the tubes give very weak light...

I haven't used the thing for some time, because I got a toneport and it's pretty cold in my room most of the time. Could it be that it just has to warm up? Please tell me that! sad.gif

Oh and I also ran the toneport signal through my amp... as phones... that was a dumb decision right..?

Do you think I'm gonna have to buy a new one now?

EDIT: the fading is gone now, I think :S

Does it work without the toneport connected to the amp?
Did you wait at least 30 seconds until you switched the amp from standby to on to warm up?

Last possibility: Do you have any effect pedals in the signal chain or in the effects loop? If yes put them all away and go straight from the guitar into the amp with a cable of that you know it works right

Nope...everything is disconnected..

EDIT: changed cable and it's better now! Still not completely the way I remember it. Maybe it needs to warm up for a longer time now that I haven't used it for such a long time.

What kind of amp are you talking about?
Is it tube? If so I would check those...

It's a tube amp. The tubes give light right? Is it bad when they shine weaker?

Yeah that would not be optimal.
If you don't play a lot at all they could last you 5 years and work for another 5 (for even longer even but they won't sound good)
If you play every day maybe they will last you a year or two.
Gigging and being very active, say 6 -12 months.

No rules only guesstimations of time to give you a target


When did you last change powertubes? If you don't know, check the amp for a tag, a good tech would write a note of it and stick it to the amp.

Try leaving it on to warm up tubes, check your cables and last possibility is to change the Tube(s) smile.gif

In future you should know that tube amps need at least 3 minutes to warm up. If you light them at once you risk to shorten the life of tubes, damage them or in worst case damage the amp's components.
I suggest swapping the tubes, they must be dead.

Absolutely, it's more than likely the tubes...

Thanks for the replies guys smile.gif

I should've known about the warming up time... I always turned it on at once! And I have played it for very very long periods of time. Ahh..! Well I've had the amp for over a year now (and it was new). So I guess it's time to say goodbye to the tubes. Maybe I will go for different tubes (if they exist tongue.gif)... Any recommendations?

It think the worst case scenario is to change the tubes...but try to give it now a daily use so the tubes get used to the work. Maybe with some days of playing through it get fixed. smile.gif

Ok, so a Valveking. You know some amps will allow different kinds of tubes, like EL34, KT88, 6L6GC. I checked the Peavey Windsow Studio rescently and it does. The Laney GH50/100 can run on EL34 or 6L6GC.

But!!!! If you're amp isn't designed for this you shouldn't! Then just stick to the same kind you got and settle for a different brand instead of a different kind. I don't know about the Valvekind but I think it'll run only on 6L6.
Tube manufacturers are actually not that many around the world which led to that many different brands are made in the same factory.
For that, JJ tubes are said to be good ones. Ask around what people think, you'll get some ideas.
