I have a Peavy TNT Bass Amp that is about 14 months old. Had it in the shop and the amp tech could find no problem with it. When it is turned up over 4 on volume it sound like the speaker is distotring very badly. At first it was intermittment, but now is worse. Could it be the voice coil in the speaker or something similar? Anyone had this problem feel free to chime in please.  |

There is a TNT 115S bass amp at the place we have our steel guitar club jams (and I played there for 14 years). The input jacks tend to be intermittent and cause problems, one of them is distortion. I've sprayed them with contact cleaner and after a while that didn't help and I had to replace them.
But, with the problem you are reporting the tech should have been able to find something. Is there a different Peavey tech you can take it to? |

Thanks Jack, There's no other tech around and I was trying to avoid shipping back to the factory. Thought I would check everything I could before going that. I will try cleaning or even replacing the input jacks. Thanks for your help.  |

Now that it's worse, take it back to the tech. Make it fail in front of them.

What are you using the amp for? Bass? Guitar? steel? Are you using anything else like a volume pedal or stomp box EFX that might be causing the problem? If You play at "3", and then slap/bang the amp hard, does it make any noise? Have you played another instrument through the amp and gotten the same result? Have you tried wiggling all the plugs and cords?
These things may help to narrow down the cause. |

| Been playing Bass only through it. I'm going to check it it out this weekend when I have a little more time to check it. One thing I did notice was the inputs are black composite or something to that effect. Would that create a problem? This amp has very little playing time, sets idle most of the time. Probably has less than 150 hrs. of on time. Thanks for the help. |

Intermittent jack switches are normally the cause of this kind of thing... each switch has contacts that close when the plug is removed. Periods of non-use make this problem worse... the contacts are self-cleaning, in that they are supposed to wipe during each insertion.
To maintain these, spray some Caig ProGold on a business card (not a shiny one!) and put between the contacts... work it back and forth.
Cheap contact cleaner/lube is not equivalent to a Caig product... simple mineral oil and alcohol doesn't help matters at all. And simply spraying the cleaner/lube on the contacts doesn't help much either... it needs to be worked into between the contacts, and the matchbook cover/business card gives the right amount of abrasive quality (i.e. not much). This is normally part of a basic bench charge/maintenance that your tech would do; road techs have been known to keep rags doused in ProGold and treat each plug before each show. It truly is magical stuff.

| Those "black" jacks are the typical jack that Peavey has used in many amps for years. The TNT115S that I reference is a 95 or 96 model and it has the same type. I've worked on other Peaveys that had the same type of Jack. I think some of the Steel amps use these types in certain places. |

You may be on to something there, Stephen. We are having problems at times with our PA system and monitors. I will find some Caig cleaner and do the Pa system jack inputs also. Thanks, I'll let you know how it comes out.  And thanks to you Jack for your support, you always have some good advise and remedies. |

Nothing says "cheap" like plastic jacks.  |
