Nashville 112 input jack problems??

[Bob Tuttle]

Have any of you had any problems with the input jacks on a Nashville 112?

[Clyde Mattocks]

I have problems with all equipment where the inputs jacks are connected directly to circuit boards. I have a Samson wireless that they don't even bother to put a nut on it holding it to the chassis. When I become Supreme Commissioner of all musical gear, this will be an offense punishable by hanging! (or death by ruru)

[Steven Finley]

sure have, had one break just like every thing
else on the piece of junk.
Have had three of them two new one used.
I gave up and got rid of them all best thing
I ever did i now have a amp that sounds better
much more reliable, lighter weight and over twice
the power.
I wish you luck, hope yours with your peavey
turns out better then mine.

As I used to be an amp tech, I've seen problems with all brands, Fender, Ampeg, Standel, etc, not just Peavey. If it's just a connection problem with the guitar cord not making good contact, spraying the jack's contacts with contact cleaner such as De-Oxit will take care of the problem.

As there are two input jacks on the NV112, do both do the same thing? Maybe it's your guitar cord and not the jack? Have you tried a different guitar cord?

[Bob Tuttle]

This problem I'm having just started recently. At first I seemed to notice a slight distortion at very low volume. This would clear up when I played louder.

Then last week at a gig I sat down to play and all I got was extreme distortion and almost no volume. I tried three different cables and finally was able to get one too work by inserting it rather hard several times. The jack connection feels a little loose and doesn't have that normal "snap" when you plug into it. The other jack didn't work any better.

I cut the ends off of all my George Ls cables and reinstalled the plugs. I checked them all with an ohmmeter. I had this same problem again Saturday night. Is it feasible to replace the jacks with standard switchcraft jacks?

[Dick Sexton]

I had one of my 112's apart yesterday reseating all the chips. I believe all of the jacks are of the switch type. The action of inserting a plug into the jack opens or closes these switch connections. I've had the very problem you have described, Low Volume and Distortion. I solved the problem on the job, by inserting a plug into each jack on the amp, front and back, several times. This action makes and breaks the switch connections enough to clean them. This could save the day on a gig. Then...

When your home, do as Mr. Stoner has suggested and clean the jacks with a contact cleaner such as De-Oxit, or any good contact cleaner that does not leave a residue. Of course, never use anything like, WD-40.

Mr. Finley is also correct, it is what it is, a cheap amplifier. What did you end up getting Steven?

[Jack Stoner]

It could be one of three other points on the amp. Each effects loop and the preamp out/power amp in on the rear. On each one of these there is a "normal through" connection on one of the jacks and if it's not making good contact (dirty contact) it will give you the exact same indication that you have.

The next time it happens or if it's still happening, plug in a guitar cord between the send and return on the pre-EQ effects loop and see if it makes a difference, if not, try that with the post EQ and finally plug the guitar cord between the preamp out and power amp in the rear. If one of these fixes the problem, the "normal through" contact on the return (or power amp in) jack is dirty. Usually just plugging in and out several times will fix these but stubborn cases require contact cleaner.

[Steven Finley]

Dick, since you asked, I bought an Evans SE200, and I couldn't be happier. Yes, it might be considered a little pricey, but re the Peavey, a bargain isn't a bargain if it doesn't work.

[Bob Tuttle]

Thanks for the replies. I'll give the jacks a good cleaning and maybe that will fix the problem. I knew that about the jumper cord in the send and receive jacks. Don't know why I didn't think to try that the other night.

[Ken Karn]

Bob, I've been having the sae type of problems.
Please post how things turn out.
Thnx
Ken

I pulled the chassis out so I could get to the jacks better, and cleaned them all with a spray contact cleaner/lubricant, then plugged a cable in and out of each jack several times before the cleaner evaporated. So far it seems to be working fine. I haven't done a gig yet, but I will next weekend. I really don't expect any more problems.

[Randy Wade]

Clyde is right about printed circuit board mount jacks. I have fixed a lot of them over the years on various brands and models, sometimes replacing the jack, but most times just re-soldering them to the board when they break loose. It's not difficult, but it is time consuming because you usually have to take every knob off and every nut off of every pot in order to turn the board upside down to get at the connections. A panel mount jack with wires running to it would be better I think.

I had a problem with the headphone jack on the rear of the Peavey (wouldn't cut out the main speaker). I inserted the jack several times and it seemed to work O.K. for now!
