Pro audio amps?

Hello, I'm am fairly new to scrapping, and these aren't on my normal list of items I deal with. I have a source that is giving me 15-20 pro audio amps (crown, and bgw brand if you need to look them up.). They all have issues, and they just want the gone. My questions. Should I try to find someone that wants to buy the, as is? Is there a market for them? Second, if I do scrap them, what should I look for of value inside? I know they weigh a ton, so getting them picked up will be fun.

I am in the dfw area of texas.

Stereo amps usually have copper wound coils (fairly large) large ic chips or transistors, a small fan or two and usually a cast alum. case.

I would look more towards retail, what I do is find out what it will scrap out at(give or take a little) and then price it just slightly higher. That way it should sell quicker than anyone else offering similar items and you don't have to spend time tearing apart. Someone might want them for parts I would think.

Usually when they blow up, the power chips/transistors burn up from overheating and a lot of times will burn the circuit board also.
And the power chips are the most expensive part of the amp to replace. Without them the rest is junk.

I have repaired and resold a bunch of power amps and older stereos. I got them for free and sold then for anywhere from $200 to $400.
Do your ebay research and see what they sell for in working order and as-is.
Word to the wise from spin....

If it won't go, check the fuse, then for obvious looking smoke marks on the board, or the main chip may have popped & you may see the side bulging or such.
Look for any leaking capactors, the cans with a plastic coating, they may have a brown gunk comming from out of the top or underneith.

Sometimes Amps are thrown out because the volume goes all crackley, same with switches & bass etc controls. WD40 may fix this, it may not too.

Its best to use a proper contact cleaner.
To clean the volume controls properly they (techs) use a small round tube that screws over the control shaft (once you remove the knob) onto the threaded boss underneith (the nut on the boss normally holds the control onto the backing plate.)
Then they fit the extension tube on the contact cleaner into a hole in the end of this tool & plug the can of spray cleaner onto the extension tube.
Then they spray the cleaner down past the actual control knob into the resistor part of the volume etc control.
That will push the oxides right out. I think they can turn the tool around so it turns the volume shaft around too, just too loosen the oxides. I have only seen a picture of them.

I think I can make something similar by just threading out the end of a bullet shell so it threads onto the control (1/8 NP?. Its 27 threads per inch) and then spraying the cleaner solvent into where the primer hole is, by drilling it out to the right size to fit the extension tube.
I could also drill & tap a small screw in from the side so it locates onto the flat on the control shaft, making it turn when I turn the tool around, while spraying contact cleaner into it.

Thanks for the good info, I have some history with this type of equipment, so I think I'm going to try and piece a few of them together for resale before junking them. I'll run by my yard today and see what he would offer me for the whole amps before I take the time piecing them out. A few of these are pretty heavy @ 40-50#. I'll post back when I pick them up on monday. All are free, so either way I'll make a buck

Okay, so I'm scrapping one of these amps. Just took it apart and the board is charred inside.

What I am wondering is, are the terminals on this (MTX Blue Thunder Pro 752) gold plated?

They certainly look like gold plated screws and blocks

Yes, The hi powered stuff will use plated components for the better connections.

I sell them "as-is" to an exporter for about 15-20$ a piece. Unfortunately I am not located in the USA :(
