Allow me to introduce myself to those of you who are not familiar with me.
My name is Tom, I'm 16 from the UK and I have been playing guitar for less than a year.
Anyway back on topic. 20 minutes ago, I'm sitting here and i put on my headphones, turn on my amp and pick up my strat.
I'm playing some nice tunes and I decide to add some distortion to practice some nice blues licks. I click my foot on my Tubescreamer only to hear no difference is tone. So the battery has run out (i havnt gotten round to getting an adapter). I decide to check in the instructions what adapter they take. It says a 9V. So i look around my room and find a 9v adapter off of something else. I plug it in to the mains and then the tubescreamer (note: I had taken out the dead battery). As I am walking to turn on my lamp and the TV off, I notice a strange smell. The smell of burning! I look at my Ts9 and smoke is slowly seeping from beneath it! I quickly turned off the mains and waited 5 minutes (just in case it was still hot or there was still current or some $@!& like that).
So whats the deal? I may be showing my lack of intellegince hear but i cant wake up my parents and have nobody else to ask.
Why the f*ck did my tubescreamer starting smoking when i hooked up the exact adapter it said to?
I hope it still works, otherwise thats like £75 down the drain!

not all 9V adapters are the same my friend. There are also amperages to worry about. If the amperage is higher than the box is rated for it can fry things.

It sucks to find out the hard way, but that's why different boxes use different adapters.

Ouch, that sucks, dude. I hope it still works for you, but it doesn't sound good.

Thats just what I was going to say not all 9Volt adapters are the same you have to look and see if it says 300ma, 500ma, 850ma, 900ma :twisted:

I'm so stupid not to realize this.
I should have read everything more careful.
I will scoure the house tomorrow for a battery to test if it works. Fingers crossed eh.
Thanks for the info everybody...

Then there's that pesky Negative Center, Positive Center thing.

It's always best to pay $10 (around £15-20) and get a Boss, Ibanez or Danelectro AC power supply AKA "Wall Wart". I learned the same lesson a long time ago, but mine just made a lot of noise, so I was lucky. You may have Fried it, but let us know if it still works. TS9's are pretty tough, I bet it still works.

I will definitely let you know.
Guess i really did learn a valuable lesson. I kinda understand why my parents always tell me to unplug things when i leave them unattended.
I'm pretty sure i got to it quite quickly, so hopefully nothing has messed up. The only thing i can say without trying it or opening it up is that it smells real bad of melting/burning.

This is incorrect. Think of the current draw of a device as a PULL situation. The device will PULL (draw) current from the power supply. The power supply (PS) does not PUSH current at a device. So a PS capable of delivering 500ma is perfectly fine supplying 200ma to a device. A problem occurs when the reverse situation is true. There can be a problem when you try to draw more current than the PS can provide. I would think that all modern 9v adapters have a chip inside that provides, among other things, current limiting -- if you try to draw more current than the PS can provide it will shut down.

When you hook up a PS to a device you need to be aware of four things:

1) Voltage - you got that part right.
2) Current - how much current does the device draw vs how much can the PS provide.
3) Connector - the type and size of connector
4) Polarity - which part of the connector provides ground and which part is connected to the positive (or negative) voltage.

I'm not familiar with the TS9 but a lot of stomp boxes uses a barrel connector with the inner part providing ground and the outer part (sleeve) providing 9v.

Take a look at the TS9 (or the documentation) and you should find a diagram that looks something like this.


Image

In this case the diagram indicates that (-) [ground] is connected to the inner part and (+) [9v] connected to the outer part.

Take a look at the 9v adapter. It should have a diagram and it should match that of the TS9. If they don't then you have reversed the polarity and more than likely fried one or more components in the TS9. If the diagrams match you can still have problems. The PS could be bad - have you ever used it with any other device? Is this this the first time you have used the TS9 with a 9v adapter? If so, you may have a defect in the TS9.

From your description (smoke and smell) I would think you did some serious damage to the TS9. Since both the TS9 and the adapter are suspect I wouldn't try to use either until you can determine the cause of failure. Now is the time to take the TS9 apart and give a give it a visual inspection. Burnt components and/or pc board should be readily apparent.

Yeah, I agree.It's probably a polarity issue. For most electrical things - if you let the smoke out...bad luck!

Hope your luck is better!

Whenever I've accidentally let the smoke out of something electrical, I usually sacrifice another chicken to the voodoo electrical spirits before I try to use it again....

Well i looked and i got the polarity wrong definitely.
But it turns out some dude my dad knows has an adapter he used to use with his tubescreamer before he sold it. So he gave it to me and i tried it. My TS9 came on (LED) but whenever i clicked the footswitch it would just make a buzzing/humming sound and didn't have any response when i hit the strings. It still allowed the sound of my guitar pass through it to my amp though.
I found the reciept so I am just gonna take it back and tell them it suddenly stopped working.
Hope it all go well. Thanks everybody for the information. Its about time I learnt these things before i set the house on fire!!

I don't feel that you should do that. You learned a costly lesson, but that is no reason to be dishonest and commit a fraud on someone else. If that is the only way you have to get your pedal replaced, send me your address and I'll see if I can scrounge you one. One of the reasons this stuff cost so much is that they have to make up for losses from bugus returns.

when in doubt, go with honesty.

Tell them what you did, and I bet they might relpace or repair it anyway.

I would have to agree. Chalk this one up to experience and be happy that this was not a £500 piece of equipment. Besides, I would think that even a half-way competent technician should be able to tell that the problem was not caused by a manufacturing defect!
