Hi all,I just received a Peavey Backstage amp from Fleabay that seems to be working (i can here a little hiss that modulates appropriately when I turn the various dials), except there is nothing going through the input jack. How difficult is it to replace these? I only spent $25 on the amp, so I sure don't want to pay a tech to fix it(!) For what it's worth, this is a Peavey Backstage Plus, 35W, c. 1980s. Thanks.

It depends on the type of jack. Some Peavey's use a standard panel mount type jack and others use a PC mount type. If it's the PC mount type you will have to get one from Peavey.But, are you sure the jack is bad? May be a wire or something on the circuit board. |

Thanks Jack,well, I think it's the jack because if I tap the plug on the rim of the jack I can hear the static registering in the speaker, but when I insert the plug the amp picks up no sound from my steel. If not the jack, I don't know how to track down a problem on the board, and as I said, for $25 it won't be worth sending it out for a repair. Is there a way to check wires on the board?? Thanks again, Dan

Dan;
I'd get my solder gun out, open the amp up, (making sure it's unplugged from the wall,) and just resoldering all the connections. Especially if any look corroded or different from the rest of them. The jack might be bad, but not too likely. Most likely a connection type problem. I've used Peavey amps since '77 and have only replaced two input jacks and one of those I broke myself. Good luck! (Hope you won't need it!)------------------
My best,
Ernie

Along with possibly resoldering, just cleaning the jack contact may be all that's required. That will cause the "static" condition. Sometimes, just plugging in and out severa times will "clean" the jack connection. Try that first before you do anything else. May not even have to take it apart. |

Thanks Jack and Ernie,okay: if I do open this thing up, can I test it with the chasis hanging out? Also, how do I tell whether it is a "PC" jack? Thanks! Dan |

If it's a "PC" jack it will be mounted/soldered directly to the printed circuit board. Yes you can test it with the chassis out, just make sure you have the speaker connected. I do that all the time with ones that I fix before putting them back together. |

I've had a similar problem swith several Peavey amps and, strangely enough, both were in the reverb circuits on the board and, after using a magnifying glass(happens after 50) and resoldering them, all is now well. |

I DID IT!!!Thanks Jack, Ernie, and Jim. It was, in fact, a PC jack, and I did need to solder it back to the board. For an electro-idiot like myself removing the board and turning it over was a major operation. Thanks for all the helpful advice guys. Dan ------------------
