Peavey Nashville 400 Maint/Repair - Do I have it right?

Jon Schimek · From: Lyons, Co - USA

Hey Guys,

I got a NV400 off the forum several years ago, but it recently started cutting out on me. I was recording and it actually cut out completely for a few minutes but it came back the next day and I'm noticing it being a bit intermittent during practice.

I've found a few older posts on the subject and it sounds like I have been neglectful in my Amp maintenance ( I didn't realize such a thing existed ). From what I gather I need to start looking at mechanical connections:
1) Check the reverb connection (consider soldering)
2) Check all Molex mechanical connections and clean/replace/re-tension

I've read that I should "clean all contacts", which I'm assuming is just using a electronics cleaner/de-greaser type product to address the above two concerns.

What else is part of "Amp Maintenance"? I work with high speed digital electronics, so I'm not too fearful of soldering, etc but I can't quite afford a new amp right now and I'm desperate to make my current amp more reliable.

I'm considering buying the Fox upgrade/mod kit, but I don't think that will necessarily fix or improve my flakiness issue.

Thanks for any tips or checklists to get max reliability out of what I have.

Thanks in advance,
Jon

The two loops have switching jacks on the inputs. Cleaning those jacks should be your first move.

Thanks for the reply and a a couple helpful PMs. I took one more stab at searching on this topic since it seems like it came up a lot. I think this thread's post from Bob Metzger should get me through the task:

For the jacks and molex connectors, always use a cleaner/lube, as just using a cleaner doesn't provide any long-term shield against corrosion. In addition, the controls will get noisy, especially if they aren't all used often, and a cleaner/lube does good things here, too. Lastly, the electrolytic caps eventually go bad, leading to hum, or distortion and lack of power. So, it's probably a good idea to replace them all if the amp is over 20 years old. Cool
