Topic: My Nashville 1000 died - fixed with patch cord? |

I started practicing at home for gig this Friday when my Nasville 1000 just died while playing. Sounded fine till then. Remebering a earlier topic on a similar problem I started trying a patch cord tying together the input and output of the Pre-Effects loop and also the Post Effects loop. When I patched the Post Effects one, it came back, and sounds fine.
Question is what would cause this and is there any problem leaving the patch cord in place when palying the gig?
Thanx,
Jim |

There is a set of contacts in one of the jacks that disconnect when cable is plugged in and most likely need cleaning...they lose connection and amp cuts out. Wouldn't hurt to keep cable in for awhile, but I would want to fix properly if it were mine.

| You might try spraying contact cleaner on the cord plug and then inserting it into each input and output effects jack two or three times. This may help clean the oxidation that sometimes forms on the jacks thus causing the problem. (Worked on my Session 400 Limited years ago). |

| The switching jack that Peavey uses loses tension over time. You may get some cleaner into the contacs with a spray, but the permanent fix is to replace the jack. (You have to disassemble the jack anyway to retension the connector.) |

Thanks for the info. I just sprayed some no-residue cleaner in the jacks as suggested, and worked the plugs in and out a few times. The amp is now working, but I will keep my patch cords handy. I will try to find some replacements jacks locally.
Thanx,

I have had brand new Switchcraft jacks in the shop with up to 1 Meg ohms of contact resistance, when closed tight. It just required cleaning. That is most often the case, especially with the power amp jack on the N400 amps. The other jacks are a plastic style and if you want to replace them I would talk to Peavey for the correct part. There are a lot of different ones made in plastic and very specific to the amp. Rarely have I ever seen a jack I had to replace, just clean and sometimes re-tension a bit on the metal style jacks (Switchcraft 12A).
This is a problem that plagues all amp manufacturers using effect loops and power amp loops. Low level signals need very clean contacts to pass thru. Another reason I never pursued using an effects loop in any amps I built. |

So, can I just keep the patch cords in all time? I do not use either of the effects loops in the Nash 1000.
Thanx,
