Topic: Nashville 1000 smokes! |

Literally.
Saturday night was the first time in 27 years a piece of Peavey gear has failed me. Unfortunately it happened on stage.
After setup and sound check, I had walked off stage for a few minutes. Just as I was walking back on, our bass player said, "Hey man, your playing is hot and all that but what did you do to your amp?"
I looked over to see serious smoke emanating from the top of my 1000. No flame, but nice thick smoke. Getting worse.
The amp was still on so I reached over and flipped the switch off. No change. I unplugged the power and eventually the smoke stopped. After pulling the chassis out of the cabinet, we discovered one of the electrolytic caps had... sorta started melting. Apparently not enough to do any other circuitry damage, however. So here's my question:
Anyone have a part list or spec for the caps used on the 1000? I can replace it myself but after examining the part closely I can't find any specs or identifying info. Peavey's web site doesn't have that level of info and I'd like to avoid shipping it back to Meridian, if possible.[This message was edited by Jeff Agnew on 17 September 2001 at 05:02 PM.] |

Jeff....
It has been my observation, if it was one of the 2 big caps (generally side by side)in the power supply section, they are both the same value. While this isn't asbslute,most of these amps have 2 large filter caps in them. |

Bill,
That's them. They're in the power supply section but there are no markings on either that I can see. Any idea of the values?
Thanks. |

If the filter caps smoked, chances are there is more wrong than just the caps. Those amps use a switching power supply, instead of a conventional rectifier power supply.
Contact Mike Brown as that amp should still be in warranty. |

| Jeff: Speaking as a decent engineer - get this thing serviced; don't do it on your own. Even a blown fuse should be replaced only when you know what caused it to go. Supply filter caps will fail if there is a catastrophic short (causing them to source their stored energy too quickly), if the supply voltage goes to high, or if there is a defect in the parts. Unless the amp was abused, I would think about demanding free service, as a burning amp is a safety hazard and the manufacturer has some legal liability. By the way (though) it's my impression that Peavey will sell you schematics for a couple of bucks. [This message was edited by Mark Cohen on 17 September 2001 at 10:32 PM.] |

Jeff,
I regret to hear that you experienced this unfortunate situation with your Nashville 1000. Our/my toll free number is 1-877-732-8391 and I am in the office Monday through Friday from 8AM-5PM CST.
In the meantime, I spoke with one of our techs here at the factory and by what you have described as the symptom, we don't believe that there is other damage other than the cap. However, the only true way to find this out is to have a qualified tech who is familiar with this technology to check the unit out.
Please contact me at your earliest convenience and I will be glad to arrange for the repair or put you in touch with our Parts Department to obtain the correct factory parts.

Thanks, Mark, for your cautions. I neglected to mention I had checked other parameters and everything seems within limits. My assumption is that it was a defective cap. The amp still worked, even while smoking. I just decided we didn't need a fog machine during a country show 
The amp has never been on the road and hadn't even been moved since the previous week's performance. While sitting nearby was my '74 Session 400, still chugging along after untold thousands of miles and hours.
Mike, I'll call you this afternoon. Thanks for your rapid response. And after re-reading my first post, I hope it didn't come across as a knock on the 1000. 27 years without a failure is a fairly decent track record in my book. |

Jeff...
Mike will follow through too. I had a little problem with my amp and he got on the phone and had me plugging in this and that to resolve it. When it didn't work, we sent the console back to Peavey and he intercepted the shipment and got it through the service department and back to me in short order.
The true test of a good vendor is the follow up when things go wrong. Peavey really tries to get it right the first time, but when problems occur they seem to jump in and help.

| I feel a need to expand my comment on liability - it is not directed at Peavey, but at you guys as consumers. As Mike Brown has already demonstrated numerous times, Peavey apparently stands by their product. If any of your gear demonstrates safety problems, the moment you take it in your own hands to try to fix things, you put yourself on shaky ground when things go wrong. |

| You're right Mark. It is very dangerous to attempt the repair on your own. |
