My 6 year old 1000 has spent the majority of the past year in the shop with some hard to find problem of breaking up and cutting out. My local tech is a former bandmate and someone I trust (authorized Peavey tech) , but hasn't been able to fix it when it plays just fine for him. He will find something that seems loose, fix it, play the heck out of it, I get it back and one song into soundcheck it craps out again. Sometimes it plays fine for a while before it starts breaking up. He sent the power board back to Peavey, they built a new one, same result. Last week he found something else that seemed like the problem, same result.
Love the amp, but at this point it's an expensive boat anchor, and I've been playing my 29 year old LTD. My loyalty to Peavey is fading, but I can't afford to buy something else without selling it first and I can't sell it in good conscience.
Anyone else have similar experience, have any ideas, or is it just me?

Are you absolutely sure it's the amp? Could be something external to the amp - have you considered that?
Have you tried the "jumper cable" on the two effects loops and on the preamp out/power amp in? to make sure it's not a flakey jack. All the "in" jacks for the Power amp in, and the two front panel effects loops have a "normal through" contact in them so that the signal is passed through when nothing is connected. When you use, for example the power amp in and plug a guitar cord into that jack it "opens up" (breaks) the circuit between the preamp and the power amp so the signal you connected with the guitar amp will then go to the power amp. Take a guitar cord and one at a time plug the guitar cord between the preamp out and the power amp in, and from the pre-Eq effect loop output to input and from the Post EQ effect output to input. If one of those is bad (and again do them one at a time) the guitar cord "jumper" will find it.
Finally, I've run across "heat" problems - when the amp chassis is in the cabinet it has the problem but when the amp chassis is removed and out in the open the problem does not happen. In those cases I use a towel or some other non conducting item to cover the amp and let it "bake" and see if the problem happens.
Some things to try or ask your buddy the tech about.
Most techs, and myself included, like to think we can fix any problem. But, I ran across one that drove me up the wall and finally I gave in and shipped it to the Peasvey factory repair center. They found the problem quick because they knew about the potential problem area and had seen it many times because of the number of equipment they worked on with the same problem. |

Thanks Jeff and Jack -
Yes, the jacks were one the first things he checked, and he has tested it all put together. He's testing it with a guitar, though, not a steel, so he suggested I bring my steel into the shop and see if we can't recreate the problem. But I think you're right - sending it off to Peavey might be the answer.
Thanks again for taking the time to respond

Peavey is not the only amp to have those jacks.
A few weeks ago I worked on a Nady PA Head.
It was cutting out after it warmed up.
Cold...the amp was fine.
With it open on the bench it worked well.
Then I put the heat gun on it.
That quickly spotted the jack which was opening up when it got warm.
I cleaned and burnished the contact also retensioned it slightly.
That corrected the problem and the owner tells me it is still going strong.

Sorry for my delay in replying, but I just returned today from the TSGJ..................
I'm kind of thinking that it is not the amp, but maybe a cable or pedal etc.. It doesn't make sense that we changed a circuit board and the problem still existed, and also it worked fine for your friend. Call me toll free at your earliest convenience and I assist. I'll be in the office after 8am CST tomorrow throughout the week and can be reached toll free at 1-877-732-8391, ext. 1180.
