Generic problem with Peavey mixers

Yes, bad design by default. The manufacturer's recommended hole sizes are often insanely oversize. This is an area my colleagues and I regularly reviewed for reliability. Connectors should not sit sloppily prior to solder and especially not so in single sided boards.

Peavey has been using these for years in most everything they make if I understand your description. I've not notice a common problem and I own/owned a lot of Peavey gear.

The one in front of me has not been obviously abused. There is a bit more rust corrosion on the rear panel connectors than I would like to see, perhaps stored in a shed or garage over a winter - but that should not produce these ring failures. Because there is no conventional rigidity locking the boards together , ie the pin arrays can move at both ends then that should be fairly immune to being heavily leant on or similar. No its oversize holes that are the problem here. The tails from each socket pin are thin strips and should have small slots , not holes the diameter of the strip and a bit, in the pcb, so no unreasonable unsupported solder. Just normal thermal movement presumably causes those to fail.

Remove one of those pin strips, remove excess solder and report back on the hole dia and the pin dia. I assume you have at least a micrometer/vernier or set of drills to gauge the hole etc.

Report back. If you can, try and identify the make of strip. Most likely Molex, AMP or Panduit.

I don't doubt your diagnosis and I have seen similar situations but I've seen a ton of those connections and very few have been problematic. I've worked on dozens of the CS- series power amps and they relied on those connections but I can't recall seeing them fail although there may have been an isolated case or two that I don't remember.

I too have repaired a lot of Peavey gear and have never come across any connector problem that might be called Generic. Peavey equipment just doesn't suffer from connector problems, unlike a lot of other manufacturers.

I suspect you just have a rogue unit.

I don't doubt that. I am saying that this is not typical of Peavey gear in general.

Peavey is what it is, but whatever it is, it does it quite well for the price. It has used the same connectors for decades and does not generally have problems with them. They are actually pretty robust. IMHO. Possibly even overengineered at that price range.

It could be, of course, that this is one design that has fallen beneath expectations. I have not seen a lot of Peavey mixers as they have never been that popular in the UK.

But, in this case we are talking about a desk manufactured 18 years ago. I'd be pretty happy with a cheap desk that lasted this long.

Gareth.

It's far from unknown for connector manufacturers to overspecify the drill size ( esp for s/s boards ).

Graham

Amen to that ! See how long a Behringer lasts.

With hindsight, all that was necessary was to press-form the tails into a near circle and use smaller holes.

Added cost.

Yes. NEVER rely on data sheet values. Seen this kind of thing all too often.

I gigged for 20 years using a circa 1975 Peavey Artist 120 1x15 combo amp and that thing was the most reliable amp I could imagine. I still have it and my CS-800 I used for my bass rig before finding a Crown Microtech 1000 dirt cheap. The Crown was a little lighter hence switching to it. I've been a fan of Peavey for 30 years just recently buying a Tube-Fex guitar signal processor needing a 3v battery for 100 buks US. Those things retailed for 900 and are still pricey used in working condition.

Or if you can persuade the company in the UK which look after them on Behringer's behalf, to even talk to you, let alone supply parts or service info ...

You got EITHER of those out of them ? Shock horror !
