brute amp clone?

[hotwheelman]

Here is a pic of what I believe to be a non tube version of the brute 70 amp. I recieved it in with some free items and it comes with issues. When powered with no signal and el cheapo speakers connected it just shoves them straight out and commences to smoke em good. What is usually the issue......bad caps?

and another view.

I'm sorry man, but the best thing for that amp would be to shoot it. ;)

Oh wait did I say shoot? Let me add this :) for the morons.

Well I thought it might be an interesting project to mod it and see what I could do with it, I just need some guidance as to what I need to do to get it up and running.

Anything and everything can be a project, go for it. It may lead to more knowledge for use on other things down the road.

I sure hope so...wish me luck, I think I'm gonna need it.:D

Poking the cones straight out means there's prodigous DC at the outputs. Assuming it has coupling caps, they could be bad; more likely IMO one or more output transistors is/are shorted out.

If it makes you feel any better, it would probably sound pretty crappy even if it were working properly.

I ALWAYS check for DC on the outputs of any SS gear I find before I risk a speaker on it. Only took me blowing out a pair of drivers on a Technics SA-202 I had found to learn to do that! Turned out one channel had something like 22 VDC on it (never blew the output fuses on the reciever, though). Speakers weren't meant to be 'always-on' electromagnets :-(
