Default burned up charger?

Something interesting just happened, I was charging some packs,3 or 4, on my Dynamite Vision Peak Ultra charger, when suddenly I hear a quick beeping sound and I see that the charger is dead (no lights on, lcd is blank). Concerned I replug it in to a couple different outlets with no change. The charger is also extremely hot to touch. I also check the fuse on the charger, it looks good. Curious as to what happened I take off the top cover and it seems like everything is intact (not that Im an expert on this). However I do notice that the transformer is extremely hot.

Here's some other info that could be useful. The charger I bought the spring 05. I had been charging ib4200s, I charged 3 or 4 packs, at 5A (the highest the charger could go). These packs were actually my first self made side-by-side pack. On a side note since the charger was working fine before I used the new packs, could I have screwed something up in building them that it could cause the charger to break? Probably irrelevant but the outlet was not protected by a surge protector and it is stormy outside.

So, any ideas as to what could have happened to my charger? My best guess, is that the transformer burned up. Anyone else have this happen to them, if so what could have caused this?

...I guess I also need a new charger...any recomendations? Im trying to go for something not too expensive.

This could have been caused by several things:

1. Improper ventilation
2. Fan failer (does it even have a fan?)
3. Power surge
4. Power supply failure*

*this is why most pro level chargers use a seperate power supply. The power supply take the brunt of the heat and when it is packaged within the same case as the charger they tend to work as a team to bake the charger using resulting in the power supply failing. Also do to packaging and size constraints most built in power supply are not of the best quality or that great at cooling themselves down.

As far as recommendations I woul buy a seperate power supply and then one of these:http://www.teamorion.com/Products/Ch...+_+Dischargers

But I am biased

MrBlack, while the charger does have a fan what you say certainly makes sanse . To make sure it was the chargers power supply I used the alligator clips on the charger to a gell cell and sure enough, it works fine. Just to make sure I'm gonna test the fuse just to make sure its not whats causing the problem (or id feel pretty stupid). If that turns out to be the case I will be looking for a power supply and charger. I looked at the team orion chargers before when I was thinking about upgrading but unfortunately the price is way out of my range...ebay it is i guess
