Champ 600 Done Broken again

Reece · Post by **Reece** » Sat Dec 06, 2008 7:47 pm

I'm clueless when it comes to amps, but basically it was all fine until I swapped around a pedal and I unplggued the patch cable and the champ went POP and started humming very loudly, I took out the guitar cable and it was still humming. I can still smell burning, I've opened it up but I can't see anything obvious wrong but like I said, I know f-all about amps.

HALP.

On closer inspection, R15 and R16 look rather fried.

Schematic

Edit: Cooked?

S'all part of the fun.

The stock tubes were quite pish so that 6l6 woulda been replaced anyway, this is odd though.
Little bastard won't stay down

Check the tube sockets for signs of arching or shorting out.

I wouldn't just replace the resistors, burnt out components is a sign something is wrong. I would get it looked at.

Yeah, I've no idea where to take it though.

The nearest shop to me is awful and they'll probably charge me an arm and a leg before they do anything.

Call Fender up?

Would they just give me somewhere authorised to take it and get it fixed?

I'm sure warranties don't carry over when you buy stuff used so it's gonna cost me either way :/.

Is it still under a year old.... If so call Fender, you take it to an authorised dealer at Fenders request they pick it up fix it and send it back to the dealer.

In America they give it to a 'qualified tech' over here they take it to one central place worked wonders for me

awww shit just read the bit about it being used..... but I'd still try it they were fantastic people to deal with.... I'm sure they'd try and help

No chance you could sort it with a multimeter and schematics yourself, or know anyone in person that could help?

As far as electric guitar amplifiers go, the Champ 600 style is pretty bog-standard. I know this one might be faffed around a bit physically but it should be the same principle. Every guitar amp company has made one at some point since the 50's.

It could be a problem with the power transformer, which would really suck.

Try replacing the resisters first since that'll be a few penny job. Up the rating a bit as well - go for at least a watt, but preferably more.

If they fry again, I think you may have a problem with the power transformer.

this is true. it is one of the most basic amps ever made. I'd still see if you can get it fixed under warranty but if that falls through it would be a great learning experience to fix it yourself.

Could proggy walk itnot he shop and never let on that he sold it? I'd assume there's still a receipt knockin gabout, or would they know your face?

Whe I blew mine up, I got a replacement without ecen asking for one. The guy in the shop recognised me and just handed me one off the shelf. I didn't even show him a receipt.

This is what I'm hoping, then I can (assuming he's cool with it) get it out to rob and he can take it in there.

I suppose you could ship it to me, and I could walk into the same shop and shout that it's fucking broke again and what are you going to do about this, eh? fucking taking the piss now, this is. Gimme some strings.
