Well, I have an Fender Frontman 15R (I know, it's shit) and it's broken. You must be thinking 'just throw it away and buy a decent amp', but I really need to practice and further selling it, because i'm thinking about buying an Roland Cube 40x (http://www.foxtrot.com.br/Produto/01040152805001/Amplificador+p+Guitarra+Roland+Cube+40+XL).

To be specific, it died because it was pluged in a 220V line and it's limit is 117V and... you know. THAT burnt smell and stuff. And I wanted help about fixing it. If there's an easy way to do it myself, I would like to hear about it.

Sorry if this doesn't belong here, and sorry for my grammar too... it's probably messed up.

You fried the power source.. Unless you've taken some course work in ciruitry, it's a drink stand now.
Out here you've gotta know where your towel is!

It will cost more to fix than buying a better amp. It sucks, but thats the way it is.

Open it up and look for burning. Those parts need to be replaced. As long as you don't also have to replace a transformer it would be a convenient way to learn.

I like the idea of learning from this.

So, resuming, if the transformer is burnt, I'll only be able to fix it by taking it to a professional to replace it. That's it?

i think his implication was that if the transformer is burnt, it wil be way too expensive to fix economically. it is the most expensive part in the amp (that amp anyway).

i suppose if it was your great grandfathers fender frontman 15 it might have some sentimental value.

Yes, I was implying that it's most expensive piece and that also it could be fried but not look like it. And you need special tools to test a transformer. I would say that if you were inclined to learning on this and you replaced all of the fried components you found but it doesn't work you could probably do some research and find out what transformer it is and maybe score a cheap(er) one on ebay.

Do you know what current the secondary needs? 30 dollars isn't too bad.. You may need a new fuses and/or electrolytic caps if they were fed too much voltage.

Nope, the fuse and the electrolytc cap are just fine. I've done some research over here and a transformer is up to R$ 90, and that's about US$ 50, so I guess it's not THAT expensive...

Well, by special tools you mean something like a voltmeter?

You'd be lucky to even get $50 for the amp trying to sell it, even if you did fix it. Like others said, it's not worth the cost, just in parts, to fix it. But if you just want practice, then by all means.

To my knowledge there are specialized tools for checking the operation of a transformer. Not just a volt meter. Maybe not specialized but I'd assume at least an oscilloscope.

+1 just play without an amp for a bit until you get the money for the Cube you might want to look at some of the other modeling amps before you buy.

The Peavy Vypyr 30 and Vox Valvetronix VT40+ are in your price range

IMHO the Vox VT40+ sounds less digital than the Peavy Vypyr 30.

Couldn't say about the Roland Cube 40.

The only Roland cube I've ever played was the 15 and I was less than impressed with it.

IMHO do some comparison shopping of the other modeling amps in your price range before you actually buy.

It sounds like this is going to a major purchase for you don't rush into it make sure the new amp you get is the one you really want.

Yeah, I was thinking about the Vypyr too. I'll check out the Vox one.

I've been wondering about the Roland because of this video, and because it's quite accessible here in Brazil. If I want a Vypyr, i'll have to import it.

The most sad part of it is to practice unplugged...
