Straightening Bent Fins

Did the sale ad pictures show the front fin as ok, not damaged ?

I know this is a fairly common thing to happen during shipping.

Really ?

It’s not severe enough that I don’t want the amp, I’m not going to send it back over one bent fin.

Those fins are thick. That amp took a real hit. What does the box look like? Is it the original Krell box?  If the box looks ok, then it happened during the prep for shipping. I would be getting it checked out and/or contacting the seller.

Unfortunately this can’t be fixed like you fix a bent boat prop.

 
Of course, you could contact Krell and ask their opinion. If it took such a hard hit, there may be additional damage. Proceed with caution.

Is almost impossible to do, any repair will always be visible  Your best bet would be to get a new heatsink and replace it.

You might want to lift the lid to see if anything else got knocked loose in shipping.

This btw is why this happens  :-)

Nice video pbn! I did a search on "Bent Fin" and it turned up many stories about others who have had many episodes like mine, most were way worse. And, looking at used amps, it's not uncommon at all to see one with a slightly bent fin from some previous encounter. It happens way more than it should. 

Yes it was in a factory box, but the foam padding failed, and the amp twisted in the box. And no it wasn't bent in the seller's photos.  This thing weighs 130 lbs, I know they weren't ginger with it. And the amp works fine, sounds amazing! No internal damage that I can see. Perhaps a new heat sink would be the way to go? If Krell even makes them or has one to sell. It's an FPB-300, not the lastest model for sure. 

I was thinking more like Erik suggested, possibly some wooden shims to prevent scratching. And applying some heat. No, not a torch or anything, just a heat gun like I use for shrink tubing. To help prevent cracking. If it's 200 degrees it would be a lot less likely to break. If my only other option is buying another, then I have nothing to loose? If, they have another. And what is connected to it? Some heat sinks have transistors attached to them, others are only against them. 

But it is a testimate to the solid build quality of this amp! It's like a tank, the rest of it is completely unharmed. No rattles or wracking, of course it feels like solid lead anyway. Wow it's heavy! At some point they should think of separate chassis, and I guess they do? I don't have to worry about some theif snatching it up and running off with it! 

so thanks guys, I guess my next step is to contact Krell.
